First off, many thanks to SAS~Bravo For giving me these instructions!!
Many steam users may be disgruntled at how DBW can't install since steam automatically updates it too far (v4.12.2m for me). However, SAS~Bravo has given an AWESOME solution that will hopefully work (checking it right now)
************FIRST OFF******************
This is gonna take a while as it involves downloading a 6gig torrent
************HOW TO GET THE FIX***********
1) Download utorrent, makes downloading the files SO MUCH EASIER!!
2) Go here:
https://www.sas1946.com/main/index.php/topic,21514.msg239532.html#msg2395323)At the bottom, there should be a link to a torrent that has this pack
4)Download that ****!
5)Install it to your root IL-2 Sturmovik folder and say yes to all to overwrite.
6)Install the RC4 patch for Ultrapack
7)Disable the Ultrapack in jsgme
8)Use the mod selector that came with the install to select it and...
9)BOOM! You now have a working copy of DBW AND UP3!
***********CHECKING TO MAKE SURE IT WORKS**********
If you see this:

The huge torrent is made for people who have the stock game and want ALL the updates and Ultrapack 3 RC4 with DBW INCLUDED in one package. However, this SHOULD work (im in the midst of testing this) with the 4.11+ versions of the game.
