How to open 12A file?

The most common problem when using Microsoft Windows is that a specific 12A is not associated with the program. This causes the file 12A to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the 12A file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Microsoft Windows

An often overlooked issue is to make sure that Microsoft Windows is installed on the computer. This can be achieved by typing Microsoft Windows into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file 12A with Microsoft Windows. Below you will find a list of applications that support 12A files.

Programs to open 12A file

Remember to download programs supporting 12A files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Microsoft Windows with 12A files

If the application is or has been freshly installed, but the 12A file still does not use the Microsoft Windows program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the 12A file with the Microsoft Windows program.

Step 3. Update Microsoft Windows to the latest version

If, despite the association of the Microsoft Windows program with the Microsoft Windows file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Microsoft Corporation page and install.

Step 4. Check for the following problems with the 12A file

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The 12A file may be unusually small compared to the original file. This is most often caused by a problem while downloading the 12A file. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our 12A file. Sometimes virus-infected 12A files cannot be recovered, so make a backup in advance.
Older version of 12A file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair 12A file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Microsoft Corporation
The program can also signal the fact of encryption. The encrypted file 12A except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. Copying the 12A file to another location will fix the problem.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file 12A to close. However, some background programs may block the 12A file while scanning. If this does not work either, restart the device.
