Problem:

Rhino crashes when I double-click a Rhino .3dm file.

Try:

Start Rhino from a desktop shortcut, or the Start menu.

If Rhino starts:

• Open a file from the File menu > Open or the Open toolbar button.
  
• If the file won't open, the problem is probably with the file. Try the Audit3dmFile command on the file.

Is the problem solved?

• Yes. Yay!
• No. Go to Crash Starting Rhino.
