I did point it to the 1946 folder , that's when I got this message , setup can not find the specified path or disk please check that the proper disk is inserted or specify a new path. That happened no mater where I directed it to go. I am at a loss.
OK, please ignore my post above ( I removed it). Sorry to lead you astray, but it was wrong. I don't even use 2.01 any more, so I was trying to remember and I failed...boohoo for me.
Anyway, Here is what I just did today.
1) Downloaded
ALL of the files (see picture below). -- I know you had issues with downloading from there, but it worked for me. If you can't download it from there, try the other links around this forum.
Once you have downloaded
ALL of the files, save them somewhere separate from your IL2 install (I use a folder on my desktop).
2)Click the Ultrapack201_Client.exe. It will ask you to specify your IL2 directory, point it to your 4.09 Install. If you have all the files you need in THE SAME folder, and it should install correctly.
I can't explain it any other way than that. Like I said, that is what I just did, and it worked first time for me.
Good luck.
