Thanks to all of you who attempted to help
I ended up talking to a computer techie person
who told me to right click on the attachment and "save as" in my
documents. I created a folder in my documents which I titled email .pps
files. I now save those .pps emails in there.
When I go to those files I simply click on them
and the existing PowerPoint viewer 2007, which was already in the computer,
recognizes the file and opens it. This is strictly a read only
procedure. To create a pps document on my own would require more
programs. We do not have office.
As for creating an "Association" which is what
the computer was wanting me to do, I am still unable to do that. When I
clicked on the attachment the computer wanted to open it with PowerPoint slide
show. In control panel under programs where I could set a default, the pps
files were listed as Windows PowerPoint slide show and the default to open them
was Windows PowerPoint viewer which is in the computer.
If you are confused, don't worry, at least we can
now open these files, but I still say darn this Vista.
