Windows 7 Power Point help

[riverposie]

When someone sends me an e-mail with a power point attachment
& i try to open it, it opens up with
a program that can not open it to view..I do have windows power point viewer, but when i click on it, it opens up my folder options & not the e-mail...How can I make all e-mailed power point stuff open up when i click on them as an attachment in an e-mail?
