VeeamPSSnapIn registration problem

[DavoudTeimouri]

Hi,
I'm using Veeam BR U2 and I get the below error when I try to open PowerShell via Veeam BR GUI console:

Code: Select all

Add-PSSnapin : The Windows PowerShell snap-in 'VeeamPSSnapIn' is not installed
on this computer.
At C:\Program Files\Veeam\Backup and
Replication\Backup\Initialize-VeeamToolkit.ps1:123 char:1

   napin], PSArgumentException

   dPSSnapinCommand

Get-PSSnapIn : No Windows PowerShell snap-ins matching the pattern
'VeeamPSSnapIn' were found. Check the pattern and then try the command again.

I have try to register the file manually but I get this:
