I'm trying to setup WebUpdate. I've followed the documentation to setup my original project and create an update project. After I install the initial deployment and my first update, wupdate.exe continues to think there is a new update and installs again. I've found a spot in the Registry where one version of my app was recorded under an old GUID that I used when I first was trying to get this to work yesterday. The current project has a different GUID, but it's not updating in the registry as an App under the WebUpdate key. I had tried so many different setting yesterday, so I checked out my original setupbuilder project again and started from scratch today, but still no luck. Should I try deleting that old key in the registry? I don't know what else could be causing this.

Thanks.
