Thanks for info Skate, I've tried all this. I even tried installing the 32bit redist but it wouldn't let me ;)
Not sure where to go with this now... running out of angles. Dependency Walker says the CPU is trying to work in both 86 and 64, its loaded the DLLs from the game folder in 64bit and the dlls from sys32 as x86, should it not be trying to address the DLLs from wow64 folder?
I'm not very computer savvy, better than most but this is beyond my knowledge.
Anything you can recommend? I've issued a support ticket to DCS World, but as I bought the game on steam I'm not hopeful of their cooperation, I'm going to download the A10C standalone installer overnight and see if I can get a 64bit rise out of that. Please note I've had the 32bit steam version working (just have to launch the game manually from the x86 bin folder). Unfortunately that isnt optimal for my nice 64bit OS and core i5/nvidia gtx 670 :(
