Same Problem... Upgraded from Win7 beta v7048 to pre-RTM v7229

yes windows 7 releases have some compatibility issues with the older versions of many softwares and hardware devices try finding the location of the file you mentioned right click and open the properties go to the compatibility tab and set compatibility mode to vista service pack 2 apply settings and try to run the program it should work now or else you will have to wait for a version compatiable with your hardware device like i did for my radeon xpress chipset
