That sounds like the old compiled help file issue. Sorry, I am only guessing here.
I had Picture it! on my old PC, and I just went and built a new desktop computer and put vista on it. I got the program to install fine on my vista laptop, but when I try to install it on my new desktop I get this:
"Cannot display the End User License Agreement which must be displayed and accepted before you can use the application. To display the agreement, reinstall the application."
It installed fine, but when I try to open it I get that, so it won't let me open it until i put in the product key, but the application wont open. And it also won't reinstall now, it just keeps giving me that error.
Is there some sort of patch I can get to get this, or does someone know a fix for it?
