Numerical order is the key. If you've got the IL2 1946 CD, you have 4.07m. Then install the 4.08m patch followed by the 4.09, 4.10, 4.10.1 then 4.11. Easy peasy. If you have something other than IL2 1946 it may be a bit more complicated.
You can download the patches right from SimHQ's mirror here: http://simhq.com/forum/ubbthreads.php/forums/265/1/IL_2_Series_Downloads.html
Thanks to all for the kind words about the article! I'm excited to see this classic continue to have new life breathed into it! Well done, Team Daidalos. Well done.
