Have you ran IL2setup.exe first?

Is it installed in the Programs folder?
If it is - create a folder in C:\ and name it Games, re-install IL2 there

Maybe it's possible to copy it to the different location and no need for a reinstall?

IL2setup.exe where is that all I see is IL2fb/original_IL2fb/gameswitcher

is the IL2fb the setup file you are talking about..

Now the screen goes black as if to try and start game then goes back to desk top
