I recently reinstalled the Quality Wngs 757. During the process it apparently tried to install another copy of FSUIPC I already had a copy installed. In any cases, when I started Flight Simulator, I received an error message stating I had multiple copies of FSUIPC. Then Flight Simulator crashed.
I went into the modules older and took a guess which copy to delete. Wrong guess. Error message. Crash.
Wrong guess. Error message. Crash.
Wrong guess. Error message. Crash.
I finally gave up and deleted all of the FSUIPC files and tried to re-install my purchased version.
I purchased it from Simmarket. (Order number: ) But not it will not accept my registration key.
Can you get me a good registration number?
