Set associations doesn't work

[Rowi]

Just got MS Office 2007, and for some reason PowerPoint is not associated to
open its own file (.pptx). Even if I create a PowerPoint presentation and
save it, PowerPoint will not open it by double clicking. It only works if I
open PowerPoint first, and then use that to open the file.

Also, I can't set the association. If I right-click on the file and select
"open with", or I go through the control panel to associate a file type with
a program, PowerPoint does not show up on the list. If I try to add it by
browsing for it, the browsing window closes and PowerPoint is still not on
the list of programs. I'm kind of at a loss. Is there anywhere I can just
type in the extensions that PowerPoint should open? Is this some bug that
anyone knows the solution to?

thanks for any help

I am having the exact same issue. Did you figure anything out? I also
cannot open old word files directly from folder but can if i open word first
and then browse for the file through word.

Use this program to add to you "opens with" window. It works!
