Hmmm. Reading the older part of this thread I realized I had never seen a manual either (DL version). But, there's no Aerosoft folder in my FSX root folder. I don't have a typical FSX installation, though. Mine's just K:/FSX. Did a search across all drives for "Manual" and found .pdf's for the Cessna, Kodiak, C-130, yada, yada, but no Aerosoft and/or Beaver. My guess is that it never installed the manual.
Lived without it this long. If I have any questions I'll just ask Steve!
