Yes, thanks for the info senseman!
I used Compression: -mlzma:a1:mfbt4:d256m:fb128:mc1000:lc8 (size of Data.cab -> 3.57GB)
Final size: 3.83GB with soundtracks, artbooks... Installation time: ~ 6 min
By the way, i will upload the v1.2:
Added eula file (english only);
New Splash with Trine 2 Goblin Menace logo;
New size for patch 1.18 + DLC;
Added new six background images for DLC;
Good idea! I will add directx 2010, but the attachment will be big
