Docx has taken over my word icons

I have tried all ways to restore my icons from docx to word. I can access word by right-clicking, but not by double-clicking. When I go to change file type associations, I select docx and click on change program. The icon changes colour, but does nothing. Anyone had this prob. and found a solution.
Thanks in advance

Try Control Panel > Default Programs. Not on computer right now; can't look. I am not sure of the exact name on the default programs panel, but you'll find it.

access to change program defaults is no problem. When I click on 'change program' on the right of the screen nothing happens

Yuk! Sorry my thought did not help.
