I got my Il2 1946 4.12m with the Ace Expansion,Pe-2 and Sturmoviks Over Mandchouria packs and I need answers to two questions :
1: What is the 4.12.2m version and where can I dl it if needed ?
2/ can I install over my ver.4.12m the 3rd paries addons : Operation Overlord and Ostfront ?

thanks in advance !

When it comes to the addons your best bet is to unpack them into a dummy folder when you can and then move the files into their correct location manually. There are normally several sound files and such that will overwrite fixes that were included in patches released after the addons were released.
