Hey fellow simmers! I've had this issue before but for the life of me can't remember how I fixed it. My FS9 runs fine, doesn't crash hardly ever. But any time I try to connect any peripheral software, like AI Separation, or weather programs, those programs say that FS9 is not running. I have done the registry repair, I have deleted all references to fs9 from the registry and did a clean install. I have tried various combinations of compatibility modes, but all to no avail. Any insights on what I may be missing? thanks
