Thanks for the reply EtherealN, glad to see it has been assigned, I'll just wait as I understand how busy things must be.
I have tried your "32 bit trick" and it did not fix the problem. I can however run all the other addon's successfully except CA if I remove the Combinedarms folder and all it's content out of the MODS/TECH folder. The problem is solely within the CA mod and not the other addons or within DCS World itself.
Hope that helps.
