Can't open Micro Soft Power Point e-mail attachments.

Hi,
I receive many e-mail attachments from Micro Soft Power Point Slide Show, e.g. When I try to open it I get a box that says something like, I need to create an attachment in my Folders Option File. I have Micro Soft Power Point 7 downloaded in my computer, but I don't know how to make it work. Can you help?
Thanks,
Slamber

Hello,

If the PowerPoint file is exported from a newer version of MS PowerPoint, you wouldn't be able to open it unless it's saved for an older version.
