  • Run the installation file applicable to the operating system
  • Reboot the computer, start Windows PowerShell and verify that the output of $PSVersionTable shows 4.0 as the value of the PSVersion property


Known issues

Installation succeeds even if .NET 4.5 is not installed

Scenario: Installing WMF 4.0 on a computer that is not running .NET Framework 4.5 will report that the installation is successful, but the components of WMF 4.0 (such as Windows PowerShell, WMI, etc.) will not be updated.

Solution: Install .NET Framework 4.5, and then run the WMF 4.0 installer again.
