Thanks for the response. I am no good at fixing computer problems. I did as the earlier thread discussed, and copied the entire 'proeWildfire 3.0' folder from 'Program Files' on an old computer running XP Pro to a new computer running 7 Home, and when I try to start the program, an error message says: "No write access to C:\Program Files\proeWildfire 3.0\bin, choose another directory for trail creation." Whatever I enter, it can't find the license. Any suggetsions will be much appreciated.
