You will want to install the SP1.1 manually then. Yours is RTM release.
Also, are you using a certified video card / driver? What is your video card and driver version?
Everytime I start Inventor 2013 version it shows me it tries to install the windows intaller inventor 2010. But I delete all other previous versions except 2012. Do anyone have any idea why I am facing this?
After installing SP1 manuallly it does not solve the problem I had. I click save after generating the mesh and it crashes. Looking for help.
Thanks in advance.
