Hello chaps i cant get the 737 to work every time it opens if FSX it crashes within 5 secs ive tried everything i know including redownloading ive had trouble with the Direct x box comes up a cabinet file necessary for instalion can not be trusted please verify the cryptographic services are enabled and the file certificate is valid, as i say ive read the forum and tried it all so much so now i cant reinstall again ive used all my activations up and can anyone tell me how to get some more activations to try and get this one up and running as im at my wits end now having tried for over six hours to see what this plane looks like.Thank youIain

Have you tried to right click "run as administrator" when you run the setup? I had the DX installation popup but mine said I had all the files. If you receive any prompts I just trust them and continue.

I will try that when i can get some more activations if thats possible do you know as well how i can get some more, and Thank you.cheersIain

Not sure if this helps but a few problems eralier led me to scrap my FSX.CFG and rebuild a new one, then tweak it with ******* and hey presto not a problem in sight ;o) Could be a shot in the dark worth trying ???

Thank you for that but ive already tried that and it did not work as well as i say im at a loss now ive been at this one for over seven hours and still the same crash as soon as it comes up in FSX.cheersIain

Is your FSX installed in the "program files" directory? If so, that could be a problem.
