I am trying to install Creo Elements Direct Modeling 4.0 on a computer. Everything installs correctly, and the program comes up, but the viewport is locked, and I get the message "vport1 frozed due to graphics error". Does anyone have a suggestion to fix this?This thread is inactive and closed by the PTC Community Management Team.
