Success!!!!!! I re-downloaded everything, the whole game and the patch using the browser next, I turned off user account control rebooted and then turned off my Mcafee real time scanning. I then started the main program to check that it started ok, closed it and ran the patch as administrator. I suspect it may have just been, as you suggested, the GOG downloader and the UAC and real time virus scanning were not the culprits however, it might have been the UAC, I have another flight simulator program and having UAC turned on prevents flight plans from being saved even though the sim tells you they have been saved.

I am currently having the same problems attempting to patch your version 4.10 to the most recent version of the Game 4.11.1 Please confirm the following as the message exchange is a little confusing.


"please make sure to unistall IL-2 Sturmovik and reinstall it after redownloading via browser."

I am not sure I understand this statement. What am I redownloading? I uninstall the game and them what do I do before installing the game again???

Hello all!!I am new to the game world,,,so glad I found GOG,,,I need to know how do you patch the games,,do you just click on the patch in the same folder after install or can you start the patch from anywhere and point to the exe file in the game,,I have few games I never patched but they run great so I never did it...Thx all...
