Hello Pete,
I've been happily using FSUIPC (registered) on FS9 for many years, thank you very much for this awesome program.
I have not updated to the latest version, my last download is version 3.99, which was done a few months back.
I've built a new PC, and upgraded to Win7 Pro 64 bit from WinXP.
I installed FS9 into it's own folder on the root directory (c:\Flight Simulator 9), away from Program Files and Program Files (x86). I right clicked on fs9.exe and told Win7 to run it as administrator.
At this point, FS9 would load and run. So, I began installing the many add-ons.
When I got FSUIPC 3.99 installed and input the key, FS9 would not run. Win7 would start FS9, showing the start up screen then show that "Flight Simulator has stopped running", and return to the desktop.
When I removed the FSUIPC.dll from the FS9 modules folder and restarted FS9, it would run.
I've got something in Win7 setup wrong for it not to allow FS9 to run with FSUIPC.dll in the modules folder, but I have no idea what that could be. I'm so new to Win7 that I feel like a noobie.
I browse through the many postings here at simFlight, and the FAQ section, searching for similar Win7 solutions but didn't see any. Not sure if my error is a signature verification issue or not.
I greatly appreciate your assistance with this problem. Let me know if more details about this new system of my are needed.
Paul
