Install to global assembly cache without gacutil

In Windows Server 2012 you can't install a DLL to the GAC by drag/drop, but you can do it using GACUTIL.exe.
GacUtil.exe is not present on the server by default.

Run your powershell and use command like sample below:
.\Add-AssemblyToGlobalAssemblyCache.ps1 FullPath\itegration.dll
This will applied in legacy windows versions
