A little help please?

The installer of 4.10 patch for default extract the files to folder:

c:\Program Files\Ubisoft\IL-2 Sturmovik 1946

But your Il-2 is in the folder:

If XP = C:\Program Files\Steam\steamapps\common\il-2 Sturmovik 1946

If 7 = C:\Program Files (x86)\Steam\steamapps\common\il-2 Sturmovik 1946

Adjust C:\ if your STEAM is installed in different place.

Extract again to correct folder. After extract the optional skin pack.
