I use this with VS2012 to install services and install DLL's to the GAC .. amongst other things. I tried the expesnive installers - they are so complicated. MSI factory literally had my service installer built, tested and working in 2 minutes. It is incredibly easy to use and yet still seems quite powerful. I'd definitely recomend this, especially if you are like me and upgraded from VS2010 to VS2012 only to find that the service installer option had been removed. Excellent intuitive software .. well done Indigo Rose.
