Mass Effect 3 (All updates & DLC's & multiple languages - 3xDVD9) - Inno Setup
It is just a modification of conversion from Fabioddq.
It is intended to be used if your game folder has approximately 26GB (multiple languages included) - it uses compression now.
Lastly It also has modified registry entries so it resembles the original installation (just in case you have a different language installation [in my case Czech] which relies on the original structure).

Instructions are similar with just single difference - move redist content to ME3_3 instead of ME3_4.

All thanks belong to Fabioddq.
