I have just installed a who new fresh system.Vista, FS9, all my addons, etc.When I start FS and select the PMDG 747, it gives me the error message that FSUIPC.DLL is too old. I checked and I have version 3.73.Tried to reinstall the 747, but that didn't work.Any suggestions to what might be the issue?UAC on or off didn't make any change.

If you don't get an answer here, go to Pete Dowson"s website at: http://www.schiratti.com/dowson.html and search his forum or post your question there.Kim

Thanks, but i fixed it.Cost me a whole reinstall of FS before I discoverd it.Entered a wrong widefs key, very annoying that the whole FS then gets mixed up, instead of just reporting an error.
