OK solved problem heres how I did it
1. Verify integrity
In the Steam GUI, go to the Library, then the game. Right-click > Properties > Local Files Tab > "Verify Integrity of Game Cache". It checks your game for corruptions and missing files, and will replace them as necessary.
2. Clear cache
In your Documents, go to the "1C Softclub" folder, then the "il-2 sturmovik cliffs of dover" folder. Within is a folder labeled "cache". Delete the contents, specifically of a folder labelled "shaders".
3. Save INI **Your control and graphics config** eg - confuser.ini / conf.ini files
4. ran dotnetFX40 and fixed install
5. ran dxsetup that came with game
both above are in redist folder
6. Install patch
Open the patch executable file (run as administrator) and point the mod to your IL2 Cliffs of Dover Folder generally located inside Program files (x86). Click OK and a status bar will show installation progress. Once complete you can close the installer.
7. ***Very Important*** Start up IL2COD until you get into the loading screen. This creates a new folder under Documents/1cSoftClub called IL2 Cliffs of Dover - Mod. The Mod folder is where you place your saved config files.
8. Copy ini files over again to main folder
The installer creates a separate folder under Documents/1cSoft named IL2 Cliffs of Dover - MOD. Please note you must move copy your controls and graphics configs (generally confuser.ini and conf.ini) from the Documents/1CSoft IL2 Cliffs of Dover folder to the MOD one as they do not have your saved configs.
i.e. the *.ini files need to be copied from
C:\Users\UserName\Documents\1C SoftClub\il-2 sturmovik cliffs of dover
to
C:\Users\UserName\Documents\1C SoftClub\il-2 sturmovik cliffs of dover - MOD directory
not from your
C:\Program Files (x86)\Steam\steamapps\common\il-2 sturmovik cliffs of dover
9. launched game set graphics resolution to match desktop , set all options to medium, no shadow, no grass, no epilectic filter vsync enabled
