Crash error 0xc000007b for AdobeCollabSync.exe when opening Acrobat

Question

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:
