There are many reasons one may want to play the original unmodified IL2. And also many reasons you may want to protect your installation DVD. Especially if you are stuck donw here in South Africa where you will NOT get a replacement if your DVD drive eats it.
(And apart from that , I am of the school of thought that anti-piracy software, measures and restrictions do 0% to stop piracy, and only punishes legitmate users)
So, here is a exe file that replaces the installation stock one, and makes you able to run the unmodded game without the DVD. It works for all DVD versions as far as I know, at least 4.05 and later.
The modded game of course has always run without DVD, but that is a whole different story, isnt it?
So, this is not a mod, as much as a crack. Use it like an adult, use it at your own risk.
I have been using it for years. This no cd crack works with 4.09m .Download
