For some time now when I click Open with from Windows Explorer's context menu I'm getting this error
This file does not have a program
associated with it to perform this
action. Create an association in the
Set Associations control panel.
instead of the standard Choose Default Program dialog. I'm getting this error no matter what the extension of the selected file is (as long as there's Open with option for given extension; some extensions do not show this option). How can I fix this?
