Software Packaging and Deployment Solution?

My company has used Sitekeeper for years now, but after a server upgrade, the application no longer works well. We weren't ever that happy with it to begin with, so we're looking for an alternative solution to deploy a few custom software packages to our domain. We really only need the packaging and deployment modules, and it must be a windows App that will run on Server 2k3. Does anyone use something similar that they may be able to suggest?

Thanks!
