If you have recently upgraded your Inventor or perhaps AutoCAD to the current 2015 only to find that the application freezes with the `eternal spinning donut’, you may have an issue with your domain environment blocking access to a Web browser task.
To get past the problem, open the Windows Task Manager and end the following process that is listed via the Process tab:
After ending the task Inventor should continue to open normally. As a work around to prevent this happening each time you start Inventor, turn of the `Show My Home on startup’ by un-ticking the selection on the General tab of Inventor’s Application Options.
You may also want to investigate any anti-virus settings deployed on the domain that may be blocking the Web browser.
