I found the solution on the IC company official website,originally posted by Codex. many thanks. and it works.
It is most likely a securom issue. Try the following.

Download the SecuROM diag tool and run a scan. Just get it to update the nessesary files and it should then run.
Last night I upgraded from Vista 64-bit to Windows 7 64-bit without doing a totally new OS install, just the upgrade where you keep all your files. After Windows 7 installed I was able to play Il-2 with zero problems so this Securom fix is probably only needed if you are installing the game for the first time.
I know it's probably obvious but I thought I would post this here since people might have a question about this in the months and maybe even years to come.
