Rhino has stopped working

I get a “Rhino has stopped working” pop up notice as soon as I start Rhino. I can see the work station behind but some unknown problem has caused Rhino to stop working seconds after opening the program. Then the Error Reporting window pops up and then Rhino closes. Any suggestions would be most appreciated. Thank you

Have you tried running Rhino on SafeMode?

How do I do that?

Here you can find some brief instructions for Rhino 5 which are still usable.

That link does not work. 500 - Internal Server Error

Never mind I figured it out. Opened Rhino from the windows start menu. Thank you for your help.
