Hi,
I have Win XP SP2 and have recently been receiving attachments that have
the
".pps" file name. I have downloaded and installed PowerPoint Viewer 2003
and
can view the file IF I first save it to My Documents and then open it by
double-clicking the saved PPS file. As I saved the file from OE, I did
not
change the name of the file in any way.

When I click it to OPEN inside OE 6, I get the error that says that there
is
NO association for this type file and to go and create one. I have
checked
the Security tab inside OE 6 options and the Block Attachments options ARE
NOT checked.

Can anyone help me with the solution to this problem. I really hate to
save
all of the slideshows before I can see them.

I have looked in the registry at the PPS file type and it is pointing to
PowerPoint Viewer as it should be.
