How to open DIAGCFG file?

An often recurring problem with Troubleshooting Pack Configuration Format is that DIAGCFG is not associated with the correct program file. Thus, when you open DIAGCFG, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the DIAGCFG 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 Support Diagnostic Tool

The first step is to check if the computer has the Microsoft Support Diagnostic Tool program installed. This can be achieved by typing Microsoft Support Diagnostic Tool into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open DIAGCFG files.

Step 2. Create association of Microsoft Support Diagnostic Tool with DIAGCFG files

If the application is or has been freshly installed, but the DIAGCFG file still does not use the Microsoft Support Diagnostic Tool program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. 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 set the program to handle this type. 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 DIAGCFG file with the Microsoft Support Diagnostic Tool program.

Step 3. Update Microsoft Support Diagnostic Tool to the latest version

The fault may also lie with the Microsoft Support Diagnostic Tool program, it is possible that Troubleshooting Pack Configuration Format requires a newer version of the program. In this case, use the Microsoft Corporation website or update the program from the application.

Step 4. Check for the following problems with the DIAGCFG file

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This suggests truncating the DIAGCFG file contents when downloading or copying. The only repair option is to download the file again.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file DIAGCFG or the program directory. However, remember that not every infected DIAGCFG file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the DIAGCFG files changes over time. 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. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged DIAGCFG files. The easiest way to restore the file is from a backup or by contacting Microsoft, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted DIAGCFG files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. It is best to move DIAGCFG to a different directory.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the DIAGCFG file again. Some anti-virus or backup software may occupy the DIAGCFG file for a certain period of time. If this does not work either, restart the device.
