I got the similar error. Have been advised in the support portal to run the unblock-file in cmd. But that didn't work. I used Powershell as admin and ran Unblock-File -Path "T:\Temp\Veeam Installers\VeeamBackup&Replication_12.3.2.4165_20251006_patch.iso"The full iso just says modify, then gives you an error that the product is already installed.
The patch says this "Couldn't load file or assembly file:///g:\Setup\ServiceOperation.dll' or one of its dependencies. Operation is not supported (Exception from HRESULT: 0x80131515)."
Trying to update from Veeam B&R 12.3.2.3617.
Do I need to open up a case?
Then manually had to stop services and veeam.shell. Otherwise the wizard will keep throwing the error.
Finally it's in progress. But my question is unlike before this update patch doesn't show that whether it's updating the Enterprise Manager or VBR. As my Enterprise Manager is hosted on the same VBR server.
