Running XP, SP3 - downloaded Free Power Point Viewer for 2007. After many trials and errors I can finally get the program to open automatically when I click on a .pps attachment in an email, but then I get multiple error messages telling me the program cannot find a file. Each time I click "OK" on one, another one pops up. The files that it is looking for are, in this order: "Document", "and", "Local", "Temporary", "Internet" and "(name of file)". It seems that the program is unable to find my Temporary Internet file folder and when I tried to find it using windows Explorer, I could not find it either. Is this a PPV problem or an internet explorer problem, or what?
