Hi Mark. I believe I tried that initially.The setting for UAC on Vista was off,on Windows 7 mine is, [b]never notify.[/b]It may be that some developers software works differently on different hardware.I'm beginning to see that more and more.I know that their are anomalies with *FLY and DX10 working on some hardware including mine and possibly with PHDG on some PC's This has been a problem with PC hardware for years because the hardware component quality is not controlled by Microsoft,whereas on MAC products,Apple controls it. Ron :D :D :D

Other than the fact that I don't use Preview DirectX 10, I have no problems with any of my addon aircraft (except one), with my UAC set on "Recommended". I have a heap of addon aircraft for FSX (you name it, I probably have it). I go into all these forums and see people having problems with their addons, and mine all work like they should. This explains why you don't see me saying much in the other forums. I just don't understand why it is that I am not having any problems (except for what actually turn out to be a real bug in the product) with any addon I buy.
