Powershell -version2 switch not working

Hello, I'm trying to run some Powershell scripts under version 2 for a Windows Server 2012 R2 that is hosting a SharePoint 2010 farm.

Things I've tried include:

  1. Changing the Powershell script path to the following: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -Version 2.0 -NoExit " & ' C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\CONFIG\POWERSHELL\Registration\sharepoint.ps1 ' "
  2. Inside the Powershell script console force the use of powershell 2 with: "powershell -version 2 .\my_script.ps1"

In both cases, running the scripts fails with it first saying that "the local farm is not accessible" and then saying "Restore-SPSite : Microsoft SharePoint is not supported with version 4.0.30319.42000 of the Microsoft .Net Runtime." when I try to run the first command.

The script has worked well for several years but a newer version of a backup software was recently installed that seems to have caused this change.

Is there a way to "force" the use of PS version 2?

    make sure your farm account has proper access.

    1. Click Start, and then right-click SharePoint 2010 Management Shell.
    2. Click Properties.
    3. Click the Shortcut tab in the SharePoint 2010 Management Shell Properties window.
    4. Input the following value in the Target field: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -Version 2.0 -NoExit " & ' C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\CONFIG\POWERSHELL\Registration\sharepoint.ps1 ' "

    If the above doesn't work, try the below one which worked all the time for me. 

    #Open Powershell and run the below commands
Start-Process cmd.exe -Credential "Domain\SP_Farm" -NoNewWindow -ArgumentList "Start-Process powershell.exe -Verb runAs" 

# And then enter in cmd.exe
PowerShell -Version 2 #for SP 2010

# Add the snapin now

    It says that it's the version of .Net that isn't correct for the Restore-SPSite cmdlet, not the version of PowerShell.

    seems like it's not the Version issue, The site you are restoring is not supported with your current SharePoint farm. either you might be using old one that will not support with your current SharePoint Farm or vice versa.
