I tried doing what the link suggested and it still didn't work. Any other
thoughts?
Are you certain you followed this bit to the letter:
Use Windows Explorer to locate a PowerPoint PPT file. Click once to highlight
it.
From the menu bar, choose Tools, Folder Options
In the Options dialog box, click the File Types tab
Scroll through the Registered File Types list to Microsoft PowerPoint
Presentation and double-click it.
In the resulting Edit File Type dialog box, double-click Open in the Actions
list.
In the text box labeled Application used to perform action, you should see
=====================
THIS ESPECIALLY
=====================
"X:\abc\def\PowerPnt.EXE" "%1"
======================
If the quote marks are not exactly as shown, it'd probably produce exactly the
result you're reporting.
=======================
where X:\abc\def\ represents the full path to the folder where PowerPnt.EXE is
located. If you don't know the exact path, use the Browse button and locate
PowerPnt.EXE.
The quote marks should be entered exactly as shown. One set of quotes around
the path to PowerPnt.EXE, another set around "%1"
Click OK and/or Close until you're back in Windows Explorer.
Now try doubleclicking the problem PowerPoint file again.
