Probably because you have an Nvidia graphics card and the wrong driver.
(about 95% of this problem is caused by this)
Most drivers before v67.22 cause IV to crash as soon as a part is opened.
Get yourself the latest certified driver from www.nvidia.com and all should
be well
If you are one of the unlucky 5% who still have the problem afterwards post
back here!

I have just purchased Inventor 10 Pro and installed it successfully, however
when i try to open a new part the program closes. Why?
