A friend of mine has a strange issue with powerpoint.
He can't seem to open any powerpoint presentations.
The message he gets is:

This file does not have a program accociated with it for performing this action.
Create an accociation in the folder options control panel.

I find this srtange because I went through quite a few steps (SEE BELOW)
and still the problem exists.
Is there something I am missing??

STEPS:
1. I made sure the presentations were coming in as .pps
2. I checked that the Powerpoint viewer was on the system.
3. I reinstalled the Powerpoint viewer in case some files were missing.
4. I verified the installation.
5. I went to Start/Control Panel/Options/Folder Options/Files to make sure the PPS was there and "Opens with" Microsoft Powerpoint.

All of the above was there, rebooted and still the problem persists.
NOTE: I also did a full sweep with a few virus scans and spy sweepers and trojan scanners and all came up clean.

Any Ideas?
Perhaps I am missing something simple??

Thanks....
