If I build the App in LV6 and install it works. When I build the App in LV7, the app will not load correctly; ie. it takes about 5 minutes to load. This only applies to Win2000 - my XP machine loads the GUI fine.
LabVIEW now uses the Microsoft installer. It's possible that you need to upgrade the version that's on the Win2K box. I think the latest service packs from Microsoft include it.
