Hello
Version 1.1 work great for me.
But after install 1.2 i make all step from pdf and after start game i see windows dos window for milisec and nothing happend.
After back to Moder 1.1 all work fine , i even dont change configuration from version 1.2.
My system : XP
AMK,
under some circumstances (this was a code problem), the Version 1.1 didn't save the memory settings.
First question for your problem: have you reactivated (through Tools / Executable Selector) the Total MODder? Perhaps in your system, it was the first time you really had memory options applied (considering that it's possible that you didn't have any before if in your computer arised the problem of the V1.1).
After starting to use the V1.2 even me started to have some problems regarding memory and huge game installation (typically called Java memory limitation), and I learnt that previously didn't have that conflict only because the activation of the game made by V1.1 wasn't complete.
So what to do?
If V1.1 worked for you, I suggest going to Executable Selector of V1.2 and Uncheck "Enable Special Memory Options". Click on Write Changes. It will create pure (non memory adjusted) versions of il2fb.exe and il2fbPAL.dll (as theorically were doing your V1.1). Check if now your game works.
The other way of action is disabling some extra airplanes to DBW from your air.ini file. And later, after having confirmed that it was a lack of memory issue, start to play with the memory parameters of the Executable Selector (usually setting the Allocated RAM to 512Mb or less) and trying to find a suitable configuration for you (not the same for everybody).
Regards,
Pablo
