First, make sure you have the right modact for 4.101 there. It is currently modact 2.72. (this one:
https://www.sas1946.com/main/index.php/topic,13832.0.html )
then, open your main IL2 game installation.
First we have to get your stock game back and working again.
So, open you main game folder.
I want you to completely DELETE the following things in there:
the whole "MODS" folder
the whole "FILES" folder
all the .exe files that are called " il2fb.exe", not other exe files should be deleted.
the whole "jsgmemods" folder
dont second guess me on any of this, just completely delete them all.
Also, delete any shortcuts to the IL2fb.exe you may have made to put on your desktop or so.
The, go to THIS topic, and download 7zip.
https://www.sas1946.com/main/index.php/topic,2123.0.htmlinstall it (if you havent already). Use only 7zip to open 7z files, such as the one the modact comes in. Some will tell you that other unzippers will do the job just as well, but they dont hang around our tech help section so much.
Now, go to this topic:
https://www.sas1946.com/main/index.php/topic,1117.0.htmlAnd download the il2fb.exe that is downloadable there. Use 7zip to open it, and put the il2fb.exe in your main game folder. It is about 4.3 mb or so big. Now, click on it to launch your game. If you had a working 4.101 previously, and you followed my steps above, then your game should start up. If it doesnt, it is because you have deleted sometheing else.
But lets assume it starts up. If it does, shut it down again.
Firstly, take the ENTIRE IL2 installation folder, (I think it is called something like "IL2 1946 Sturmovik" or something,) and COPY AND PASTE the whole thing to somewhere else on your PC. This is so you have a backup. you dont need the CD to play the game anymore anyway, you can copy and paste as many installations as you like.
Then, take the downloaded modact 2.72, and use 7zip to unzip it to some folder where it is alone. If your download is corrupt, 7zip wont open it at all.
So, unzip the download. Inside, you will find exactly 11 items.
a folder called "DGen"
a folder called "FILES"
a folder called "jsgmemods"
a folder called "MODS"
an exe Called Il2fb.exe
an exe Called JSGME.exe
a dll file called wrapper.dll
an INI file called JSGME.ini
an SFS file called SASBasic27.sfs
an SFS file called SASSound01.sfs
a file called Readme SAS Modact 2.7.txt
if you have anything else, or anything less, then you either did not use 7zip, or is not PC savvy enough to own a pc anyway.
Now, select ALL 11 items. COPY and PASTE them into your IL2 sturmovik installation folder. (the one where the il2fb.exe is)
When your pc tells you that you will overwrite files, say yes, overwrite them. If you miss any part of the modact, you are stuffed. make sure you copy all 11 items in.
then after that is finished, click on your il2fb.exe to launch the game (this will now be the new one that came WITH the modact, about 150KB or so big), to launch the game. IF you did everything exaclty as I said, it will start. If you negleted any step, or tried to keep some old mods or files, or decided for yourself to leave out pieces of the modact, then it will not start.
Beware iof you have a nanny PC, that hides files. IF you copy and paste and your PC tells you there are hidden files that it is not copying, you better make them visible and copy them. Il2 has some odd files in, and it is possible that something could have gotten missed.
IF you struggle with that, the physically drag and drop the files into the game folder.
Follow the steps and let me know how it goes.
