Wipe all traces of Wind River from your computer, take out your software CD's from the kit.
Install WindRiver again, make sure to add the license file (I forget the exact name but it's some text file that the installation will ask for, it's on Disc 2).
Don't open WindRiver yet. Restart your computer just to be safe. Download and run

Restart the computer once more and attempt opening WindRiver. If you're still getting errors I'd recommend calling FIRST support and they'll direct you to the necessary department (might be external to FIRST).
Phone: (603) 666-3906 or (800) 871-8326 (via

Hope I was of help, because it's a licensing issue you might want to cleanup registries after the uninstaller ~ I'd recommend

EDIT: Oh, and of course since you're in Vista, right click on the run shortcut of WindRiver->Properties->Compatibility->Run as XP SP3 and Run as Administrator.
