BUG: The certificate for the WMF 5.1 setup has expired WMF 5.1 cannot be installed
The certificate for Win7AndW2K8R2-KB3191566-x64.msu has expire and installing WMF 5.1 fails with the following error in Event Log/Windows Logs/Setup
Windows update "Update for Windows (KB3191566)" could not be installed because of error 2148204801 "A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file." (Command line: ""C:\Windows\system32\wusa.exe" "C:\Users\username\Downloads\Win7AndW2K8R2-KB3191566-x64\Win7AndW2K8R2-KB3191566-x64.msu" ")
Is WMF 5.1 still supported?
Thanks for the report. We are working to address this.
Don’t have an ETA at this time, but it is being actively worked on.
ANd its still not fixed. Typical Microsoft.

It is crazy that this still isn't fixed!!! I am unable to install WMF 5.1 because of this.
I have tried installing 5.0 instead (trying to update from 3.0) and there is also a certificate issue.
Do you have a workaround to install PowerShell 5.1 on a Windows 7 machine?
