Hi
Sorry there is no way to get Combat flight simulator 2 running on Windows 10. And to try forcing Windows 10 to except the cab files from the game this will make for a un reliable windows. So not an option
If you still have your Windows 7 media or disk drive try running a Virtual machine , Hyperv if you have windows 10 pro or Virtual box if home version. Come to mind.
I have an old windows 7/XP dual boot computer which was a high end gaming system about 8 years ago which is ideal when you want sometime playing older games.
