Good news !!!!!!
hi Umberto,
YES, Finaly its working...no fresh install ! i finaly found a solution !
In a few words : UTX had to be REinstalled.
the problem : without notice i couldn't launch fsx anymore...CTD
errors messages : fsx crash because of : g2d.dll , api.dll , g3d.dll , ntdll.dll , KERNELBASE.dll
effects : exe.xml , dll.xml got corrupted, some others softs won't work as well ( UT2, GSX , Vfxcentral...)
the solution : 1) arrange the exe.xml and dll.xml files
2) remove the scenery.cfg in fsx main folder...see if it works, fsx will create a new one.
if fsx makes it then you have a problem with a scenery problem. i noticed that were i didn't have UTX or GEX , fsx was launching.
I was changing the airport destination quickly before CTD.
3) put back the old scenery.cfg and remove the new one ( empty ! )...be aware, make sure you have the same scenery.cfg all the different place they are ( fsx\,c:\ programdata\ ,c:\users...,
c:\all users, fsX\Setup\XPackCache....they have differents nemes (*scenery*.cfg.*...)
4) disable all UTX and GEX and try if fsx launch...not in my case !
5) uninstall all UTX...try fsx...in my case no CTD. don't uninstall GEX ! just disabled.
6) now repair all you can before reinstalling UTX like : GSX and vfxcentral ( needed a reinstall ) , that's all. not UT2.
here, if you have fixed your exe.xml and dll.xml...those soft in trouble may find their way back.
7) verify now that fsx is okay, that all your airports are showing
reinstall UTX opus 1 by 1...after each one verify if fsx launch in that area after each one installation !!
9) ENABLE GEX step by step , 1 area at a time like for UTX
10) after this , no more CTD because of g2d.dll...
Now, all my planes are running except that the pictures are not corresponding to them.
And, launching them is actually reinstalling some dll or exe files needed...so , it's okay.
WHAT has caused the trouble
??
here are the things which might be the cause :
1) some textures that i dangerous to resize within fsx
2) i did a realignment process on the fsx HDD with a special tool within System mechanic
3) 3 repeated CTD flying : kord to kjfk
4) something mixed up closed to kjfk because of too much narrowing and different textures : kjfk , GEX, UTX , NE new york , NYcity of DD ( in which i was disabling 1 then 2 bgl in order to evade OOM )
It is because of those CTD closed to kjfk that i was disabling those bgl in DD NYcity (NY_large_N.bgl and NY_large_S.bgl ).
5) uninstalling and reinstalling System mechanic.
NOW , i must find a way to fix the pictures when selecting aircrafts...better than a whole fresh installation of FSX !
I hope this may help some one in this trouble.
here is a picture of kjfk , Ne newyork city, UTX ,GEX , GSX, REX, and DD NYcity opus without the 2 bgl !!!!!
thanks.
