I am trying to install Windows update for Installing Windows PowerShell 4.0. The Update is : Windows6.1-KB2819745-x64-MultiPkg.msu at This Link
Following are my system Specifications:
I already have prerequisites to install WMF 4.0 which are SP1 and .NET 4.5.
I get a simple plain error with no details that update can not be installed.
what can i do to install this particular update?
Just in case anyone want to know, I need to install this update to Install KVM required for building VNext Apps.
