Problem solved! Thanks for the help. Just deleted the old fsx.cfg and let fsx to rebuild it. And no more api.dll CTD.

I dont think that thats the problem. It crashes on loading.

I dont know what to do. My fsx is crashing every time that i install a new addon, and always is because API.DLL I'm running FSX + SP2 on DX10 mode (DX10 Scenery Fixer). I dont have my pc overclocked. Might be a issue with FSUIPC? What i can do?

I'm using Windows 10, i'm on windowed mode.

Hi, sorry for my bad english. Today, trying to tweak my FSX again, i set some configs on Nvidia inspector and also in my CFG. I have never used DX10 Before. I try using an cfg that i found on internet to see if that give me some extras fps, but no, so i delete it. This CFG had the DX10 active. Next to that, i try to build a new cfg. When FSX started, the screen when the aircraft preview were was black. I tried everithing, deleting my cfg, deleting the Shaders, the Nvidia inspector config, etc. But nothing worked. I'M DESPERATE! For me, unistalling everything and reinstalling isnt an option. I have a lot of freeware and payware addons, so, that would be VERY hard and tedious. PLEASE HELP!!
