OK, don´t call me stupid...

I have now tried to install the patches properly, but it still says 4.07 in the startup!!!

well then, I'm sorry but I have no idea why that is..
If you can see Norway as a map in the Full Mission Builder you have the content from 4.08m and if you can see SM.79 as a flyable plane you have the content from 4.09m..

if not then I can't help you any further

If you are sure that you have pointed to the correct folder, the problem could be that you have said no to overwrite already existing files in the Il2 folder.

The file ''files.sfs'' ,for example, is replaced with each patch.

I didn´t get any prompts!

You're right, the 4.08 .exe selfextractor does not ask whether to overwrite or not.

You said you tried to extract the patch content to a temporary folder, and then move it from there to to your main Il2 folder. If you moved to the correct folder you definitely should get a prompt that some of the files already exists there.

Is it possible that you acidentially extracted or moved the files to one of the subfolders in the Il2 folder?

Can you check if you have these two files in your main Il2 folder:

fb_3do18.sfs
fb_maps14.sfs

They are part of the 4.08 patch.
