Find the file folder that contains the game it will probably be under program files or in the ubisoft folder. right click and copy this folder and paste it on your desktop. Rename the folder to something like IL2 modded. Now go to add and remove programs and tell it to remove IL2 from your computer. After it has completed the uninstall go to the ubisoft folder and delete any files or folders that the uninstall didn't get. If you go to your folder that you saved on the desktop and double click on the IL2 executable it will run your modded version. You can now do a clean install of Il2 on your computer and run this version from its executable, which will be found in the ubisoft/IL2 1946 folder or something similar.
