VeeamPSSnapIn not found

[Jim Mc]

Hi,

I'm getting a similar issue to http://forums.veeam.com/powershell-f26/ ... t5870.html

Veeam B&R 8 update 1. Just installed the BPS_x64.msi from the ISO.

When trying to run some basic tests I get the following:

PS C:\Users\xxx> Get-PSSnapin VeeamPSSnapIn
Get-PSSnapin : No Windows PowerShell snap-ins matching the pattern 'VeeamPSSnapIn' were found. Check the pattern and
then try the command again.
At line:1 char:1
+ Get-PSSnapin VeeamPSSnapIn
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (VeeamPSSnapIn:String) [Get-PSSnapin], PSArgumentException
+ FullyQualifiedErrorId : NoPSSnapInsFound,Microsoft.PowerShell.Commands.GetPSSnapinCommand

The DLL Veeam.Backup.PowerShell.dll doesn't seem to exist in the Veeam installation directory @ c:\program files\Veeam\Backup and Replication so I can't register it manually.

I've tried uninstalling and reinstalling the BPS_x64.msi from the ISO and selecting all features are installed locally but it hasn't made any difference.

Help appreciated.

Hi,

Finally tracked it down, it seems the directory they suggested it was located in in the previous thread wasn't quite accurate, it's actually in:

C:\Program Files\Veeam\Backup and Replication\Backup\Veeam.Backup.PowerShell.dll

So I try to register it manually and get the following error:

Code: Select all

set-alias installutil $env:windir\Microsoft.NET\Framework\v2.0.50727\installutil.exe
installutil 'C:\Progra~1\Veeam\Backup and Replication\Backup\Veeam.Backup.PowerShell.dll'
Microsoft (R) .NET Framework Installation utility Version 2.0.50727.8007

Exception occurred while initializing the installation:
System.BadImageFormatException: Could not load file or assembly 'file:///C:\Program Files\Veeam\Backup and Replication\B
ackup\Veeam.Backup.PowerShell.dll' or one of its dependencies. This assembly is built by a runtime newer than the curren
tly loaded runtime and cannot be loaded..

This is on Windows Server 2012 R2

Hi, James,

What happens if you instruct PowerShell to utilize a later version of the CLR? Will that help?

Thanks.

[Jim Mc]

I had a quick browse of the guide but haven't actually attempted the instructions because:

Code: Select all

PS C:\Users\xxx> $PSVersionTable

Name                           Value
----                           -----
PSVersion                      4.0
WSManStackVersion              3.0
SerializationVersion           1.1.0.1
CLRVersion                     4.0.30319.34209
BuildVersion                   6.3.9600.17400
PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0}
PSRemotingProtocolVersion      2.2

Which should mean the 4.5 CLR is loaded? Version number ends in greater than 17000?

[Jim Mc]

I just realised it was the 'installutil' alias pointing to the old CLR, the following got it working:

Code: Select all

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\installutil.exe 'c:\progra~1\veeam\backup~1\backup\Veeam.Backup.PowerShell.dll'

followed by:

Code: Select all

PS C:\Windows\system32> add-pssnapin veeampssnapin
PS C:\Windows\system32> get-pssnapin veeampssnapin


Name        : veeampssnapin
PSVersion   : 4.0
Description : This is a PowerShell snap-in that includes the Veeam's cmdlet.

Thanks.

[veremin]

As far as I know, uselegacyv2runtimeactivationpolicy should be enabled and both 2.0.50727 and 4.0.30319 versions should be listed as supported runtimes. Those changes should be reflected in PS configuration file. But that's more like a first guess. Thanks.

It seems that the installation of snap-in went wrong, thus, the absence of it. Let support team review installation logs and find out the root cause of the described behaviour. Thanks.

How wrong can the install of msi go?

Simple reg file does it:

Hi all,
i looked at C:\Program Files\Veeam\Backup and Replication\Backup and there are no Veeam.Backup.PowerShell.dll. version Veeam Free 8.0.0.2030
There are only Veeam.Backup.SanPlugin.Hp3PAR.PowerShell.dll, Veeam.Backup.SanPlugin.HpP4k.PowerShell.dll, Veeam.Backup.SanPlugin.NetApp.PowerShell.dll, Veeam.Backup.PSService.dll
which of dll i have to register?

[ITManager]

Great solution, after spending many hours the regkey file finally fixed my problem.

Thanks,

Amazing how much BS there is about getting this to work and something like this is what it takes. Run the installer from the original media and then create a .REG file with this code and merge it with your registry. Thanks so much for posting this.

[flesz]

Thanks a lot , the registry file fix it.
I spent 2 hours trying to make it to work, tried repair and other solutions in this post, none of them worked, except the reg fix

[riahc3]

The reg files does not do it for me either.

[Marco Bulk]

Try to look for the correct path where the DLL file is located. Change the reg file accordingly and that should fix your issue.

Old, but I had this problem with Veeam 9.5 update 1. This reg worked for me:
