PowerShell not working after 6.5 upgrade

[rhnb]

I'm having a bit of a mare with the 6.1 to 6.5 Veeam upgrade.
Started with Enterprise Manager which no longer works and have a call in about that (00160624) - it's been escalated apparently.
While the guy was looking at that today he updated Veeam B&R to 6.5 to see if that would fix the Enterprise Manager issue. That seemed to go OK, it didn't fix the EM issue, but my backups are working. However it's broken Powershell (which I use to stage off to tape at the end of each job). I've been through the whole run the setup / 'Modify' thing and ensured Powershell stuff was selected, but its not playing ball.

Have tried registering the DLL and got a bit further but it's saying that it can't load VeeamPsSnapin as the 'assembly is built by a runtime newer than the currently loaded runtime'.
Any ideas how I get the VeeamPsSnapin registered or whatever to get this working? I assumed the install would do all that.
I can live without EM for a short time but not having the tape staging functioning is causing me problems.

The easiest fix for this problem is probably to install PowerShell 3.0, but you can also probably just run "C:\Program Files\Veeam\Backup and Replication\Install-VeeamToolkit.ps1" as well. This post documents the most likely issues, and solutions, fairly well.

If PowerShell is the only issue, then I will merge it with the existing topic (or at least, move to the correct subforum).

Thanks for the pointer re Install-VeeamToolkit.ps1 - that's fixed it for me.

Still haven't got EM working yet, but support are on the case.
Cheeers...

I also had a few issues with my powershell reports http://forums.veeam.com/viewtopic.php?f=26&t=13422 after the 6.5 upgrade.

Also solved with the Install-VeeamToolkit.ps1 script.

Thanks.
