Enter the following command reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\full" /v version. Check the displayed version. If the version 4 is not installed, install Microsoft .NET Framework 4 from here.
    • To check if PowerShell is installed, type PowerShell from Run. If PowerShell is installed, check for its version number by running the command $PSVersionTable. If the version is below 5.1 or if PowerShell is not installed, install PowerShell V 5.1 from here.
