I have the same problem. I can install Archicad 14 edu on Windows 7, 64-bit, without problem but I can't open the program. The welcome (start up) screen is shown and some seconds later the grey program background is shown behind the welcome image. After this the program hangs (Not responding). My computer meets all specifications given at
http://www.graphisoft.com/support/archicad/system_requirements/. I have also tried to install it with antivirus/firewall (windows security essential) shut down. Other CAD-software like AutoCad Architecture and SolidWorks runs fine.
Can anyone suggest a solution? Thanks!
