No snap-ins have been registered for Windows PowerShell

[veremin]

Challenge

While adding Veeam Backup and Replication snap-in, PowerShell returns the following error:

“No snap-ins have been registered for Windows PowerShell version”

Cause

The issue is typically caused by presence of two PowerShell instances (32-bit and 64-bit ones) inside 64-bit operating systems and is related to one of the following situations:

• • Snap-in has been incorrectly registered (or has not been registered at all) for the improper PS instance either automatically or by user via instautil
  • User tries to add 64-bit snap-in from 32-bit PowerShell instance
  • 64-bit PowerShell shortcut is wrongly pointed to SysWOW64
  • Usage of Windows 2008 (R2) with default Powershell 2.0 (there are a lot of weird issues related to it)
  • etc.

Solution

Several possible approaches are suggested:

• • Opening VB&R snap-in via icon in VB&R GUI, Menu -> PowerShell (as described here)
  • Manually registering snap-in
  • Checking corresponding registry hive and manually re-creating missing entities (as described here)
  • Updating default Powershell 2.0 in case of Windows Server 2008 (R2)
  • Reinstalling the latest Update, along with PS snap-in
  • Reinstalling everything from scratch (mostly applicable for those who are on free product version, as there is no historical data, configurable infrastructure, etc. ; might be a tough call for those who are on paid product versions)

More information

If neither of the suggested solutions does the trick for you or you have further questions, open a support case, as follows:

• • Go to the Customer Support Portal
  • Click the Get support tab
  • Open a case

Thanks!

I notice we don't need to register the snapin for newer versions of Powershell. I'm using Powershell 5. This might work for older versions too. I simply copy all files/subfolders of c:\Program Files\Veeam\Backup and Replication\Console
to another server anywhere you like. Then use import-module directly with Veeam.Backup.PowerShell.dll

import-module D:\scripts\Powershell\modules\Veeam\Veeam.Backup.PowerShell.dll

Now if you run get-module, you will see Veeam.Backup.Powershell listed

To get the list of commands available just run
get-command -module Veeam.Backup.Powershell

I haven't tested all the functions but they seem to work fine for me

I've been checking differet ISO Images but i can't find the Setup-File for the Powershell Module, atleast in the Backup Folder there is no BPS-File.

Where can i get a download link? Or is it possible to extract the Snapin from the Powershell Module?

I wanna create a Dokumentation Function so that i can create a report about the current Veeam Server with its Job etc. pp.

Hi Oliver and Merry Christmas!

Starting from v9 Veeam PS Snap-in is integrated in VBR installation package.
So, with the current version, if you want to create your custom function out of Veeam powershell cmdlets, you would need a server with VBR instance running.
Anyway, internet abounds with various Veeam reports. I'm sure you can find the one fitting your goal.

Thanks,
Oleg

Adding to what Oleg mentioned, you can also install the Veeam PS Snap-in on a different server by installing the Veeam Backup & Replication Console. The screenshot below was taken from our PowerShell documentation.

Be aware that starting with Veeam Backup & Replication 11 there is no Veeam PowerShell Snap-in - it has been superseded by Veeam PowerShell Module.

Previous PowerShell scripts that attempt to load the snap-in will fail with the error "No snap-ins have been registered for Windows PowerShell".

To resolve the issue remove the following line from the existing scripts:

Code: Select all

Add-PSSnapin VeeamPSSnapin

Thanks!

I found the best way to go about this issue is simply calling this function before doing anything related to Veeam.

Code: Select all

function Setup-VeeamPreflight {
    <#
    .SYNOPSIS Setup Veeam B&R connection reliably, www.rausys.de
    #>
    $InstallPath = Get-ItemProperty -Path "HKLM:\Software\Veeam\Veeam Backup and Replication\" | Select-Object -ExpandProperty CorePath;
    Add-Type -LiteralPath "$InstallPath\Veeam.Backup.Configuration.dll";
    if (-Not(Get-Command Connect-VBRServer)) {
        Add-PSSnapin VeeamPSSnapin;
    };
    try { Get-VBRServer | Out-Null; } catch { Connect-VBRServer; };
};
