I am operating Windows Vista on a Toshiba Laptop It is an Intel(R) Core(TM)2 Duo. 2.00GHz 4GB Ram.
The graphic display adapter is ATI Mobility RADEON HD 3470. I had been running Inventor 2012 without any trouble.
Is this an installation problem, or somethihg else? Looking at previous posts I can see others have had the same sort of problem with earlier versions.
It's almost certainly your video card. ATI = Always Trashes Inventor. I suspect the laptop does not meet recommended requirements. You can check to see if there is a newer video driver. I wish you luck.
I have the same problem on my HP Workstation. Win7,64. The graphic display adapter is NVIDIA NVS300.
Start with this driver:
