From what I understand, the new security features of Vista will prevent a config file being written in the Program Files folders of Windows. I'm not sure if WL writes them there but if it does it would explain why it won't run with Vista. An undate will be needed by Davis to make it compatable. Does anyone know if this might be the issue here?
Quite possibly. It all has to do with user account control and whether or not virtualization (a workaround for legacy apps trying to run in Vista) is turned on, what priviledges the program is running with etc. I would help to know the specific error that is being seen.
