Upgrade to MS Entra Connect Sync fail

I am trying to upgrade my Server 2022 to the latest verions of MS Entra Connect Sync and it fails. with error 14001.   Researching it shows to Repair the Microsoft Visual C++ retistributables.   I have done that without success.

 

a KB said to uninstall all MS Entra Connect and it uninstalls the remaining components.   However, the repair doesn't resolve the issue.  I tried to uninstall the Microsoft viual C++ 2015-2019 as a note said MS Entra would install it again, but it does not.  I try and install a fresh copy, however, I can't find the site to download.  Where can I find this download version.  Any other clues on fixing the error 14001.  I do have full system backups to restore if needed

microsoft visual C++ 2015-2019 Redistributable (x64) - 14.29.30036
