Thanks for all the tips.
So I copied my prestine cdrom with falcon4 to an usb stick at work the 1stday I was there.
Tried to launch the installer that evening at home … it loaded but as soon as I selected setup the screen went away and nothing happened.
I did not booted in safe-mode to try again.
So I dropped some money on steam … for less than 4euro atm it was. Installed fine and launched it once just to exit as soon I was once in cockpit. Then launched the BMS-self-installer 4.37 … worked perfect with NO warnings.
Did some setup changes to alter it to my 5120x1440 with 240hz screen and all detail to highest … and had some +350fps during the 1st flight but man … am I lost again … need to complete relearn (forgot it + 15yrs ago I played it last) how to fly this plane and use the engine , radar, weapons,… But man, the impact THIS wide screen give is soooo huge compared to 2560x1440.
Thanks again for all tips.
