WMF5.0 Prod Preview (KB3066437) installation problem
BUG: WMF5.0 Prod Preview (KB3066437) cannot be installed anymore on 2012 R2
Since yesterday when I launch WMF5.0 Prod Preview (KB3066437) installation an error message box show up : "the timestamp signature and/or certificate could not be verified or is malformed"
Indeed : Microsoft Time-Stamp Service certificate is out of date : 20/06/2016 !
How can I install this Preview version without changing date time on the server (SQL Production server !) ?
The best answer is to use the WMF 5.0 RTM bits.
WMF 5.0 Production Preview is no longer supported, as explained in this blog: https://blogs.msdn.microsoft.com/powershell/2016/05/23/end-of-support-for-windows-management-framework-wmf-5-0-production-preview-is-approaching-upgrade-to-rtm-bits/
WMF 5.0 RTM is a significantly more stable version than WMF 5.0 Production Preview.
