I am trying to upgrade Veeam B&R Community Edition from v10 to v12.1 on a Windows Server 2012 R2 physical server. During the upgrade process System Configuration Check the result shows that Microsoft Powershell v5.1 requires a reboot, and the installation process will continue after reboot. After I reboot the installation process begins again from the beginning, resulting in the same message. So this has created a loop.
I manually installed Powershell 7.1 but it appears the OS considers this a separate version from the original Powershell 4 version. So it doesn’t appear that the B&R installer realizes PS 7.1 is installed.
How do I get around this installation loop? I have tried uninstalling B&R and starting from scratch, but the same issue appears.
TIA
