did everything as you said, but still the same result. FS9 crashes on start.
As I've said, if FS9 QUITS on start (it's not a crash, if you don't see any error messages), it means you have not installed the current version of the Addon Manager. And, since the installer automatically gets it online, the only possible explanation of not getting the currrent version, is that the antivirus is blocking its installation so, you are still on the old one.
Please repeast my previous instructions to the letter, don't skip ANY step. It's really important you run the installer with the antivirus TURNED OFF entirely, with the real time protection off, not just its user interface turned off.
AND, that you exclude the FS9\MODULES\BGLMAN.DLL file from scanning BEFORE running it for the first time.
