My installation of Visual Studio 2003 Enterprise Architect doesn’t run through… I tried it twice and there’s a point where the current action is shown as “Removing registry entries” or something very similar to that, and that’s where suddenly some msiexec process starts gobbling up a lot of CPU and never terminates. Killing that process makes the setup process fail, but I don’t get any detailed information about the real issue, probably because the problem isn’t recognized by the MSI system. I’ll go with 2005 for the time being, but I hope I’ll find out later why this happens.
