If you follow the PowerShell Team blog – http://blogs.msdn.com/b/powershell/ (and if you don’t you should) you’ll know that the WMF 5.0 RTM downloads were pulled just before Christmas. This was due to a bug that reset the module environment.
A comment on the blog – http://blogs.msdn.com/b/powershell/archive/2015/12/23/windows-management-framework-wmf-5-0-currently-removed-from-download-center.aspx – from the team indicates that it’s likely to be a few weeks before the bug is resolved and WMF 5.0 is available again for download.
