PST Capture: Unable To Detect Windows PowerShell 3.0

PST Capture tool require “Windows PowerShell 3.0″as a prerequisite.

If you are on windows 2012 or R2 then you don’t need to install “Windows PowerShell 3.0” separately because it comes preinstalled with windows PowerShell 4.0

When we run the PST capture we might see the following message which means PST capture is unable to find out “Windows PowerShell 3.0”

“You must have windows PowerShell 3.0 installed in order to install this product.”

You will try to download and deploy it but it will fail because “Windows PowerShell 3.0” is already installed.

  • Go to this website and download ORCA from the bottom of the page.

  • Run the setup as administrator the click next

  • Select Yes and click next

  • Click next here

  • Click next and next here

  • Click finish once done.

  • This will launch the program.
