Symptoms

Game fails to launch - product code not added to Windows registry. Splash screen loads then game crashes to desktop with Bad Serial Number error

Reproduction

Install Take On Helicopters on Linux, then launch.

I have managed to fix the issue manually by installing Take On Helicopters on Windows 10, then running regedit and exporting the key HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\bohemia interactive studio.

I then imported this key into the Linux version and launched the game successfully.

Start with the attached steam-65730.log and reproduce the launch failure for Steam AppID 65730. Compare the reported missing registry product code with the manual registry import described in the issue. Done means Take on Helicopters launches without the Bad Serial Number error after a normal Linux installation.
