Hi, my problem is to run tools (gbviwewr or GTXViewer). When I run the program this error appears: [Only registered and activated users can see links. Click Here To Register...]

I guess that it's about net framework version etc.. my system is Windows 7 Ultimate 64bit

Please help and provide links. thanks.
