I think that I solved the problem in part.
First problem=SH3 Commander r3.2.
I made a wrong multi installation of SH3 Commander r3.2.
I made new Installation of GWX 3.0 Gold avec cette nom: "SHIIIGWX3.0GoldSH3CommanderMEDITERRANEO"
I made a scond installation of SH3 Commander r3.2 in this way:
I create a folder called "SH3Commander r3.2-Mediterraneo" and I installed Commander into this folder.Then I installed SH3Cmdr Config files for GWX3.0
But This did not work at all.
I do not know why the previous installation of Commander and the new installation of Commander are mix

So when I launch=Start Commander I have a CTD
Second Problem:
Aces' Multimod compatability fix v1.6 beta.
You
MUST HAVE (ALL) the following mods enabled:
GWX_DFa-Flag&Pens_2010, FM30_UpDown_final, FM_NewInterior_V1.0, Conning Tower open Hatch TestFMfood, Depthcharge Shake v2.01, Urfischs_ModStrike_Beta1, Waterstream+Exhaust Combi V2.3 for GWX3, to ensure correct operation.
And I do not have:
FM_NewInterior_V1.0
Conning Tower open Hatch TestFMfood
Which are really nice ones but I canīt install īcause I have only 2GB of RAM and If I install those ones I have no more than 5-10 fps.
So when I launch=Start I have a CTD īcuse I do not have Enought RAM.
Now Iīm gonna try only one installation of SH3 Commander R3.2 and all the mods Except "Aces' Multimod compatability fix v1.6 beta".
