Fix Application Error 0xc000007b

This error prevents the user from launching the application.

Cause

The cause of the error is when the 64-bit applications on a 32-bit system or vice-versa. It is very common after installing Microsoft Office.

Try the following solutions to fix the issue:

Solution 1 – Re-install DirectX

1] Press Win + R to open the Run window and type the command C:\Windows\System32. Press Enter to open the System32 folder.

2] Delete the files “xinput1_1.dll”, “xinput1_2.dll”, “xinput1_3.dll” and all files starting with xinput1_*. Please be very careful not to delete the wrong files or the system would start facing new issues.

Re Install DirectX

 

3] Once these files are deleted, delete them again from the trash folder so they do not exist in the system at all.

4] Go to this link and download DirectX.

5] Install DirectX and restart the system.

 

Solution 2 – Re-install the .NET Framework

The .NET framework does not need to be deleted prior to re-installing it. Simply download it from this link on Microsoft’s website and install it.

Solution 3 –  Re-install your Application

Re-installing the application as intended here needs more than simply un-installing it from Programs and Features and installing it again. We would suggest using Microsoft’s own or other third-party tools to scrape off the application and all its components completely.





To remove Microsoft Office, we could use the tool mentioned at Option 2 on Microsoft’s support website here.

Once uninstalled, install the program again after ensuring the exact version of your system.

2] Select System from the list and check the System Type from the data mentioned, whether it says 32-bit operating system or 64-bit operating system.

Solution 4 – Check hard disk for errors

We can check the hard disk for bad sectors and other issues using the CHKSK (Check Disk) command.

1] Press Win + R to open the Run window. Type the command cmd and press Enter to open the Command Prompt window.

2] Type the command chkdsk c: /f /r (where c: is your system drive) and press Enter. It would ask whether you wish to scan the hard disk or not. Press Y and then Enter.

Run Chkdsk

Restart the system. It will check all bad sectors on the hard disk and try to resolve them. By the time we finish these solutions, we would have exhausted troubleshooting every possible cause of the error and hope it resolves the issue.
