Crash error 0xc000007b for AdobeCollabSync.exe when opening Acrobat

I have a user who is constantly getting an error popup when starting Acrobat.  Sometimes the user is able to click OK until it goes away, sometimes it wont work.  Its an Application Error popup with code 0xc000007b and the process is for AdobeCollabSync.exe which is weird because this only happens when the user launches Acrobat so I assume another Adobe application was not uninstalled properly?  This is what I attempted so far:

 

  • Uninstall/reinstall Adobe

  • Repair all Microsoft Visual C++ distro packages

  • Uninstall/reinstall all Microsoft Visual C++ distro packages

  • Use the Adobe Creative Cloud Uninstaller

  • Use the Adobe Clean Uninstaller

  • Clean the registry with third-party registry cleaner CCleaner

  • Windows updates

 

Any other ideas?

The error code 0xc000007b is a Visual Runtime error code not Acrobat. Reinstalling will not fix.

If you have updated Visual C++ try running System File Checker to see if there is corruption on the system:

I forgot to mention I also did a System File Check but any versions of C++ in particular my users should have?  My latest user had the x64 and x86 versions of C++ 2010, 2012, 2013, and 2015-2022.

Just to confirm, this is the clean uninstall tool to use correct?

1. yes, that's the cleaner page

2. your answer: "Yes it did not solve the issue" is ambiguous.  

 

do you mean uninstalling, cleaning and reinstalling per https://helpx.adobe.com/download-install/kb/uninstall-reinstall-acrobat.html failed to solve the problem?

 

if yes, the problem was not solved and you see the same microsoft error, why did you mark a correct response?  was that an error?

Yes it did not solve the problem.  The error pop-up when launching Acrobat still persists.

I did not mark it as a correct response.  I assumed you or an admin marked it as a correct response.
