>I've heard alot of good things about InstallShield, and I'll probably switch over to it for the next quarter's product update/release. What's the difference between the full/Express versions and where can I get it?

The Express version is less expensive and easier to use. It should fit the most common installation needs. I was able to get my installation program ready in a couple of hours ! Just the matter of defining your groups, drag and drop the required files and click the desired options...
