There is a single mega-patch that patches the game from stock 1946 to v4.10.1, then you can just go from there.

Make sure you first have WinRar or 7Zip.

Has anyone else noticed there might be a problem with sound attenuation? I did a quick 4v4 in the quick mission builder, and the gunfire from my wingmen a kilometer away sounds like it was right next to me. Same goes for their engines.

Behaviour of Gliders
 

I was able to set waypoints for gliders (G-11) so, that they landed in desired place in 4.11. Behaviour of gliders is fully different in 4.11.1 in the same mission. Now when trying to set waypoints for gliders I cannot avoid direction changes of gliders before landing. I have no idea what causes the changed behaviour of gliders. Is there any help or advice? Thanks for the patch, regards

Can you please post the mission? That would help understanding and tracing the problem.

Thank you for your reply. Here is the mission. Gliders land in places indicated as landing waypoints in 4.11. In 4.11.1 they change the direction before landing. This is related to gliders starting with delay in air, not to gliders towed at start of the mission by He 111 (because Ju 52 cannot tow gliders, which is a pity). Chosen time is according to daylight setting in 4.11. Result: in 4.11 a correct mission related to a historic event (Eben Emael, of course), in 4.11.1 a historically incorrect disaster for gliders. I tried to fix it by changing waypoints of gliders, but no chance to avoid direction changes of gliders before landing in 4.11.1.

Very late to the party, just want to say thank you TD for your excellent work!

I had 4.11.1m installed in H:\Games\Steam\SteamApps\common\IL 2 Sturmovik 1946\. I then ran [REL] 4.11.1, and installed it to the same location. The version is displayed as 4.11.1m, the same as it was prior to installation of the patch. Have I installed the release version properly?

4.11.1m is the lastest version of the game. The [REL] is just a tag to indicate that the thread contains a new release version (the same you already had installed).

So, you did nothing wrong, it's just that you had the game already patched to the last version.
