When you install the 4.09m all worked .
Then when you install the HSFX-V4.0 make sure the install
GOES to the correct game path or folder.
the same goes for the HSXF-V4.1. Watch it close.

DO as Skyomish says. I tried three times in all and it was to do with the directory it was pointing too. With each install of HSFX, make sure you point to the IL-2 Sturmovik 1946 as the last line in the selected folder.

Mine is C:\Program Files\Ubisoft\IL-2 Sturmovik 1946.

What I ended up with the first time was a mess and nothing launched except for Vanilla 4.09. Got it sorted now and it was worth the time to get there IMHO
