Hi Gerri57,

Nope. If Steam or GOG ever forces 4.14.X (or later) on players I will revisit the Unpatcher.

4.14 in the meantime remains a voluntary install, meaning that at some point you had access to 4.13.X and you should be able to get a copy of 4.13.X again.

Was able to revert the GoG version back to 4.12.2 with this.

Got the original DVD but it apears damadged/corrupted so got the GoG version wich should make things a lot easier in the future.

OK, I had the same problem others, or maybe it was just one other.... had trying to run this "Unpatcher".... but read below for long-ish solution (simply copying/replacing files may have worked but only the writer of the bat would know....

I uninstalled my good old HUGE IL-2 1946 from my win7... E: drive (I never stick games on the c drive, probably why my drives last so long)... and Installed the GOG version I got way back (4.13x).

No Luck when run as .exe as administrator- weirdly I think it "knew" where my IL-2 was located and didn't ask me to browse..?.... it looked correct -  but SADLY game still says 4.13.X.

Downoaded the zip file to try the other method - ran it stupidly without reading the instructions to move the folder (WHICH isn't made unless you tell your unzip prog to make it) .. it pretended to work and did nothing of course.... deleted everything except zip file and unzipped into folder with correct name and moved to same location as my game exe... then ran again... NO LUCK ... still 4.13.X.

Noticed I could not the bat "run as admin"- check box greyed out everywhere - Found others with the same problem on both win7 and win10 and like me they said right click run as admin PRETENDS to work... but NOT.

Screw it I say... I'm either manually copying the unzipped files (probably won't work since why make a batch file ?  But you never know it takes all kinds.... or running from CMD prompt...

Decided to run through command prompt as admin and of course with the crazy path and file names it refused to cooperate one bit.

LEARNED A NEW THING... simply copy "cmd.exe" into the folder containing the bat file (or a shortcut might work)... and the PATH comes out correctly... Now tried again... NO LUCK running... IT HATES THE BAT FILE NAME with all the spaces... RENAME TO "unpatch.bat"  simply write that full file name in your command prompt and enter..............

IT WORKED AND GIMME A BEER IMMEDIATELY......... In case anyone runs into my same problem give this a go.

 Hi cant get my game back to 4.12.2 so i can install the mod.
 Make sure IL-2 is NOT located in your /Program Files/ folder (*)
  Run as Admin
  Point it to the folder where il2fb.exe is located
   See other guys had the same thing happening to them here.
  I see in IL2 Sturmovik 1946 folder, the Direct-to-Drive Patch folder
  And i see the files fb_3do.sfs
  il2_usgs.dll  il2_usgs2.dll  msvcp71.dll  msvcr71.dll
  i have the game in steam Library i extracted the patch with 7-zip.
  Start the game in steam and see V4.13. still show's
  So what im i doing to not have the V4.12.2 show up?
  HELP please. working on this for 3 hours . lol dont tell any one
  A DAY LATER NOW: And got it all working. So to get your game back to V4.12
  Go to STEAM in Steam the game hit Properties.. Betas Particpation . you see pop down window
  or what ever its called . Click that. you will see V4.12 you will roll back by Steam

so here we have two different tools one is just to convert your il-2 version 4.13.4 to 4.12.2 this is the unpatcher exe file that you need to point to the root folder of il-2 (the same folder where Il-2fb.exe is located). Once the unpatcher has finished his work just try to launch il-2 to verify that everytihng works.
The direct to drive patch is not always needed however you may want to try it in case il-2 has problem launching after the unpatch.
