Im looking for ways to push software to my 350 users. I have an SMS server setup, but dont have the ability to create packages. I can create GPO's and point them to the software install. I need to install Project 2003, Visio 2003 and Ultra-Edit v14. The 2 MS are already MSI packages and should work through GPO, UE has a reg file that needs to be imported after install I'm not sure how to do that through GPO without creating a new installation package?
What software (open source?) is available to create installer packages? What other options are there to push software installs to a Windows XP / 2003 network?
