i have il2 1946 installed with 4.09 beta patch.
also i have a battle over europe, with the 4.21
patch.
i downloaded enjoypatchaskins 3v-1-0 and installed them to il2 sturmovik 1946/paintschemes/skins.
when start a campaign and select a new skin for my aircraft the choice seems to be only the existing default skins.havei installed the patch in the wrong folder.

I usually find that when extracted to the Skins folder, the actual skin is in a folder within a folder. I have to move the skin up a level in the correct aircraft folder so it is viewable just by opening the aircraft folder without having to open another subfolder. Then it appears in the game.

I then delete the intermediate, now empty subfolder. These add up after a while and take up disk space.

Hope this helps. Good luck.

All EnjoyR patches should be installed in the game's main folder (root), and not in any sub-folder...
