Can you show what you entered to run the script? The only two parameters accepted by that script are AcceptEULA and AllowRestart.

unpacked it and run the file in it with "Execute with Powershell" in context menu.

Might be an extra switch in the context menu. Extract the script to a folder. Then start Powershell with "run as administrator". CD to the folder. Hit tab and it should autocomplete the .ps1 file name. Run it that way.

From the installation instructions for WMF 5.1:

After extracting the ZIP file contents, open PowerShell as administrator, then navigate to the folder containing the contents of the ZIP file.

Run the Install-WMF5.1.ps1 script in that folder, and follow the instructions. This script will check the prerequisites on the local machine, and install WMF 5.1 if the prerequisites have been met. The prerequisites are listed below.

Install-WMF5.1.ps1 takes the following parameters to ease automating the installation on Windows Server 2008 R2 and Windows 7:

AcceptEula: When this parameter is included, the EULA is automatically accepted and will not be displayed.

AllowRestart: This parameter can only be used if AcceptEula is specified. If this parameter is included, and a restart is required after installing WMF 5.1, the restart will happen without prompting immediately after the installation is completed.

Answer 1

Hello Thank you for your question and reaching out. I can understand you are having query\issues related to Windows Management Framework 5.1 update using script. First of all Please check below depencdoes or requires are full filled. Latest service pack must be installed. WMF 3.0 must not be installed. Installing WMF 5.1 over WMF 3.0 will result in the loss of the PSModulePath ($env:PSModulePath), which can cause other applications to fail. Before installing WMF 5.1, you must either uninstall WMF 3.0, or save the PSModulePath and then restore it manually after WMF 5.1 installation is complete. WMF 5.1 requires at least .NET Framework 4.5.2. You can install Microsoft .NET Framework 4.5.2 by following the instructions at the download location.

Yeah, all of this is fulfilled, i'm trying to update WMF 2.0 to WMF 5.1 and have .NET Framework 4.8.03761 and earlier ones. And it still does not work.

Oh my god, im so sorry for everyone here, i thought that the KB3191566 update is something that's needed for installation, turns out it is a WMF 5.1 update itself, i just was confused with error, that didn't even considered to check the update in Powershell. Im so sorry, thank you so much.
