What you need to know when installing applications on a memory card
It is easy to notice that almost all Android applications, after downloading, are installed in the smartphone’s memory. This is explained by the fact that the memory card is a very unreliable place to install and save programs on it. And that's why:
- Data on the memory card is stored without encryption
- A low-quality card can disrupt not only separate application, but also the entire system
- If you remove the memory card, you may lose all applications installed on it.
- A broken memory card also leads to the user losing data.
Features of older versions of Android when using an SD card
Throughout the history of the Android operating system, one can trace three large periods in solving the question of how to install applications on an Android memory card:
- Android 1.1 – Android 2.2 Froyo
- Android 2.2 Froyo – Android 4.2 KitKat
- Android 4.2 KitKat – Android 6.0
Before Android version 2.2 Froyo, there was no way to install, save or transfer applications to a memory card at all. On technical forums one could find several purely hacker ways, but only advanced users could use them.
Starting with Android version 2.2, developers allowed installation and transfer of applications, as well as saving to a memory card. To do this, it was enough to find the Applications item in the operating system settings and set the storage location.
At the same time there appeared various programs, which could be downloaded for free from Google Play, allowing you to transfer already installed applications to a memory card. But similar utilities required assigning root rights, so not all users could cope with such a task.
When developing the update for Android 4.4 KitKat, Google specialists were seriously concerned about data security and rewrote the security algorithm. Installation, saving and transfer function installed applications The card was generally blocked. The SD memory card on Android has become exclusively a storage place for photos, videos and other content.
Developers could make updates to a particular program that would allow them to bypass Android security systems and save programs to the card. This did not completely solve the problem of installing, transferring and storing applications.
How to install applications on an Android memory card versions 6.0-7.0
The ability to install or save an application to a memory card appeared only in the sixth version of Android - Marshmallow. The developers created a feature called Adoptable storage, which helps to “make friends” between a reliable internal drive and an unreliable external card.
The adaptive storage function allows you to format the memory card so that Android perceives it as part of a single system partition. This happens with the help file system Ext4 and 128-bit AES encryption. The memory of your smartphone is becoming more spacious, and you can use absolutely any memory card.
Experts recommend using high-speed cards marked Class 10 and UHS-I Speed Class 3. Adapting memory cards has one significant pitfall. The card becomes part of one system, in fact, part of Android itself. Accordingly, when you delete it, there is a risk of losing all applications and data stored on it.
If you bet on new phone card from the old one, be sure to check it for malware using a special antivirus utility. You can choose the most reliable one for yourself using our article about the best antivirus software for Android.
How the Adoptable storage feature works
In order to understand the principle of operation of the adaptive storage function, we will analyze all the main steps step by step:
- Install a memory card in your phone
- A dialog box for setting up the memory card will appear. Here the system will prompt you to choose one of two settings: portable memory or internal memory
- Selecting internal memory for storing data (applications, files, etc.)
- To protect your data, the card must be formatted. If there is on the map important files, you will need to create a backup copy of them
- Go to the Android settings and select the “Storage and USB drives” section. If all the previous steps were completed correctly, you will see your card in the list of drives.
Please note that from the very beginning you will not be able to install the application on your memory card by downloading it from Google Play. By default, it will be automatically installed in the internal memory of the Android smartphone. However, by setting up a memory card as an internal storage device, you can transfer and save programs to it. To do this you need to follow a number of simple steps:
- Go to Android settings and select Applications
- Select the application you want to transfer to the memory card
- In the program settings, click on Storage
- Here click on the Change button
- Select SD card and click Move
After a few seconds, the selected program will be transferred to the memory card. Please note that if you remove the card from your phone, you will lose access to the application. If you still need to remove the card, go through all the above steps and assign the storage location to the internal drive. Now you know how to install applications directly onto a memory card. And you can tell about your successes in the comments to this article.
In this article, I will tell you about the ten most common reasons why programs are not installed. You will learn about the symptoms of a particular cause and will be able to diagnose and eliminate it yourself.
So, let's go - ten reasons why programs are not installed on Windows.
The most common reason why programs are not installed is the lack of a system library NET Framework required version. This library contains resources that are needed for the normal operation of a particular program. Therefore, if it is not there, then the program will not be able to install.
It is recommended that you install all versions of the NET Framework on your computer, starting with 2.0 and ending with the highest version that your Windows supports. This will ensure normal work all programs compatible with your OS.
To find out which NET version Framework is installed on your computer, click on the “Start” button, select “Control Panel”, then open the “Programs” section, and then “Programs and Features” (example for Windows 7).
You can download the versions you are missing on the Microsoft website.
As a rule, if programs are not installed due to lack of required NET Framework, a message appears indicating the version that needs to be downloaded.
Lack of Visual C++ and Direct X required version
The next common reason why programs are not installed is the lack of Visual C++ and Direct X components. Visual C++ is necessary for programs written in the popular C++ language, and Direct X is required for most games. As with the NET Framework, there is different versions these components.
You can find out the version of Visual C++ in the same way as the NET Framework - in the “Programs and Features” section.
And in order to find out the version of Direct X, click “Start” and open “Run” (or ctrl + R). Write down the dxdiag command and click OK.
As a rule, if the program does not install due to the absence of these components or their correct version, a corresponding message appears. Required Versions Visual C++ can be downloaded, and Direct X.
Incorrect Windows bit depth
Windows can be 32-bit or 64-bit. For 64-bit OS You can install 32-bit and 64-bit programs. And at 32 bit systems will only work on 32 bit program. Therefore, you will not be able to install a 64-bit program on it.
To determine the system bit size, click right click to "Computer" and select "Properties".
The bit depth of the program can be found in its description. If it is not suitable, a corresponding error will appear during the installation process.
Damaged installation file
If, when installing the program, an error appears stating that the installation file is damaged, you should obtain this file again. This can happen due to the fact that the program file was not fully downloaded, or was posted on the site already damaged. To solve the problem, you need to try to download the program installation file from another location.
Missing required DLL
A rare reason why programs are not installed is the absence of some libraries in the system that should be there by default. This happens if you use unofficial build Windows or these libraries were removed intentionally.
The problem manifests itself in a message that complains about some DLL file.
To solve it, you need to download the required DLL file and place it in the desired directory (in system32 or SysWOW64). You can download the libraries.
After this, you should register the library. To do this, click “Start” and select “Run” (or press ctrl + R). Then write cmd and click “OK”. IN command line libraries are registered with the command regsvr32 file.dll, where file.dll is the name of the library file.
Program build curves
A frequent reason why programs are not installed is the crooked hands of pirates who hack them and give them to you. free use, or somehow modify it, that is, make their own assembly (repack). To avoid this, read the comments of those who have already tried what you are installing.
It is difficult to say what errors may occur when installing such programs. It could be anything.
Without administrator rights
If you work in an office, then you may encounter that your user does not have administrator rights. Your System Administrator may intentionally prevent the installation of programs. To solve this, ask him for help.
This can happen not only in the office, but also at home if your user on the PC does not have administrator rights.
Blocking by security programs
All computers have antiviruses and some software can be blocked by them. This is also a common reason why programs are not installed. The solution is simple - disable your antivirus or other security program and install the program. If necessary, add this software to the trusted list in your antivirus or security program.
Be carefull. If you are not sure of the reliability of the source of the program, then it is better not to install it if the antivirus complains.
Conflicts with older versions of programs that were not completely removed
If you are updating a program version and first uninstalled the old one, and then try to install a new one, a conflict may occur if the components old version were not completely removed. This often happens when using the standard Windows uninstaller.
To fix this problem, you must remove all components previous version manually. You can also use cleaning programs, such as CCLeaner.
Equipment disadvantages
Today there are programs and games that can no longer be installed on all computers. So they can present special requirements to video cards, random access memory, processor.
You won’t be able to solve this problem by downloading some files. Here you need to upgrade your computer and buy additional hardware.

If applications are not installed on Android, then the first thing you need to do is restart the device. Perhaps the cause of the error is system failure, which will be fixed when you restart Android.
If after restarting the program from Play Market still not installed, look for other causes of the malfunction. We will talk about this further.
This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.
Why is the application not installed on Android?
The main reason is the shortage internal memory smartphone or tablet. If your phone doesn't have enough memory, it can't save installation file application and install it. There are two ways to fix the problem:
To see where applications are installed, go to the “Memory” section in the settings. At the top there will be an item “Installation location”, when you click on it a list will appear with available options. In order for applications to be installed on a memory card, you need to select it in this list. In this case, the system will download the installation file and store application data on microSD. The storage location does not matter - it will work equally well from a memory card and Flash Player, and Viber.
Increase This option is not available on all devices and depends on the shell provided by the smartphone manufacturer.
Another one possible reason installation errors - unstable internet when downloading the installation file from the Play Market via 3G. Connect to Wi-Fi hotspot to ensure a connection at normal speed.
If the application is installed not from the Play Market, but simply from the Internet in the form of an .apk file, then the reason the system refuses to install it may be incompatibility of the firmware or blocking by the antivirus. It is recommended to install applications only from the Play Market that are suitable for the Android version on your phone/tablet.
In addition to problems with the application, errors in the operation of your Google account may also occur. To fix them, delete your account and add it again.
- Open settings, find the “Accounts” section.
- Select Google.
- Click on the account you are using.
- Expand extra menu and select “Delete account” (note that the data associated with it will be deleted, you will need to make a backup copy).
Increase After deleting your account, restart your smartphone. At next switch on add your account again and try downloading applications from the Play Market.
As a last resort If problems arise with installing applications, you will need to reset the settings to the factory state or reflash the device (relevant for phones with custom, not official firmware).
How to install applications correctly?
Every user should know how to on Android different ways- via Play Market (Google Play) and APK file. This allows you to reduce the number of errors when installing programs and makes it possible to choose a more appropriate method for each specific situation. To install an application from the Play Market:
- Run Play app Market on Android. If you haven't added yet Google account, the system will prompt you to create a new account or specify your existing profile information.
- Dial in search bar the application you want to install.
- Open the page of the found application. Make sure it is compatible with your device and click Install.
- Accept the required permissions.
- Wait for the download and installation of the program to complete.
Increase After successful installation, a notification will appear indicating that the application has been installed. Open it to check it's working. Similar steps can be performed on a computer using the Google Play website.
- Open the Google Play website in your browser. Log in to the account that is added to your phone.
- Find the app, make sure it's compatible, and click Install.
- If the account is added to several devices, select the phone on which you want to install the application.
Increase The main condition for installing the program remotely is connecting your phone to Wi-Fi. Through mobile traffic the application will not be downloaded from Google Play.
Manual application installation
If you want to install the application from third party source, and not from the Play Market, then the first thing you need to do is prepare the system.
- Open settings, go to the “Security” section.
- Find the item " unknown sources» and put a tick next to it.
Increase Now you can download the APK file of the application to your computer and transfer it to your phone memory. You can transfer the file in any way - via USB connection, by mail, via Bluetooth. The main thing is to remember the folder where you sent the APK.
Users of mobile devices with Android systems are often faced with the need to move some information from the internal memory to an SD card. After all, even resources modern models, the volume of ROM (internal memory) of which reaches 4–6 GB, over time will no longer be enough even for useful applications– not to mention gaming ones. The way out of the situation is to move programs to external storage one of the suitable methods for this, or installing applications and games on a memory card (flash drive) on Android.
Option for older Android OS
Operating Android systems, released before the release of version 2.2, did not allow moving applications and games to the memory card either manually or using special utilities. This could be done using unofficial firmware. Or by gaining root access to the system.For mobile device with version 2.2 and higher, you can use the settings to move applications from memory to card and vice versa. Although the installation location of the programs is still determined by the developer. And see if you can free extra bed on internal media or not, you can by doing the following actions:
- Opening system settings;
- By going to the application menu and opening the properties of one of them;
- Clicking on the “Move to SD card” button. Its absence means that the manufacturer has prohibited the transfer of information.
The reason for prohibiting transfer to a card is the large throughput internal information storage. An application located in memory will run faster and more reliably compared to running it from an external drive. And without getting root rights, you won’t be able to move it.
Using special applications
A program called AppMgr (or App 2 SD), like several other utilities that do not require “superuser” rights, does not allow you to move system information. You cannot use it to install onto the SD card those applications for which this action is prohibited by the developer. But for programs that could be transferred manually (for versions 2.2 and higher), the process of changing the location is simplified.All applications are divided into three groups in the AppMgr manager:
The simple interface of the file manager and the ability to transfer several applications at once from one storage to another speed up the process of freeing the ROM from unnecessary data. And they allow you to see the big picture, rather than opening the settings of each program one by one. The result is increased device performance.
Method for new systems
Starting with Android 6.0 OS, users were able to use an SD card as internal memory. This allows, first of all, to expand the size of the device’s ROM, and, secondly, to immediately transfer applications to an external drive, without manual or software transfer. To configure the card you need:
After the system reboots, part of the ROM will be stored on external map. Dimensions internal storage will become larger, but on the outside, on the contrary, there will be less space left. And when you download the program, it will automatically be installed on the SD card.
