Hello, I'm new user of and would like to experience the features of Navisworks freedom 2014, I downloaded the free download Navisworks 3D viewer 2014. When I am openning the program a screen appears that a "software problem caused the naviswork program closed unexpectedly". I try to uninstall and reinstall the program but still the screen appears with a problem. My system is windows 7 home premium and all graphics are updated and comply all the system requirement to run this program. Can you help me with this..
