I have tried all the following recommended solutions but error still persists,
- Reinstalled Windows 11 enterprise
- Edited the registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MMC\SnapIns. and deleted the CLSID folder
- Made sure that .NET Framework 3.5 is installed
- Renamed the mmc.exe in C:\Windows\System32 and ran the sfc /scannow to check and repair corrupted system files.
Please help, I need to setup the Azure backup !

Based on the information shared, I understand that you are facing issues with MARS agent. In most cases, it could be a transient issue. However, in your case this appears to be a problem that needs attention, and I suggest you "Download the latest version of the Azure Backup agent" this should help resolve the issue. If this doesn't work, then try to remove below reg key and retry the operation.
Note: It is recommended to back up the registry key before making any changes to it.
"HKLM:\SOFTWARE\Microsoft\MMC\SnapIns\FX:{84AF3E24-7EE9-44C9-8007-3B5093D6D208}"Hope this helps! Let us know how it goes.

2024-11-28T07:59:19.5466667+00:00 @SadiqhAhmed-MSFT Thank you for the response.
I have tried installing the upgrade from the link that you gave me and the error was the same.
So I edited the registry and removed the "HKLM:\SOFTWARE\Microsoft\MMC\SnapIns\FX:{84AF3E24-7EE9-44C9-8007-3B5093D6D208}" as suggested, but now I get this error
Please advice, thank you.
