Using Windows 7, Home Premium, 32 bit. No Office 2007 installed. Using
Microsoft Works. Have experienced several issues with Office PPT Viewer 2007.
Cleared them, but additionally each time I try to open a .pps file, either
from the Desktop or Windows Mail, I receive the following:

"C:\Users|AMD\AppData\Local\Microsoft\Windows\Temp oraryInternetFiles\content.IE5\E7D22GOW\Gathering
of Mustangs and Legends2007.pps is not a valid Win32 application".

I have opened this file many times on another computer, so don't think it is
an issue with the file. The software has been uninstalled and reinstalled
several times, with a reboot each time. Also redownloaded the software two
different times thinking it was a corrupted download.
Can someone direct me towards a resolution, so I can open these files?

Thank you,
