Disassociation .pps in Vista

[firedrill]

I use PowerPointViewer to read .ppt, .pps files in emails. It works fine for user-A, but does not work for user-B in the same computer. This is because .pps is associated to wrong programs in user-B. PowerPointViewer does not show up as a program in "control panel / default program", so I can't correct this problem.

There is a great article from mydigitallife which I thought can solve my problem:
http://www.mydigitallife.info/2008/0...windows-vista/

But I can't make it to work: For both users, Assoc & ftype looks the same
Assoc .pps
.pps=PowerPointViewer.SlideShow.11

ftype PowerPointViewer.SlideShow.11
PowerPointViewer.Slideshow.11=C:\Program Files <x86>\Microsoft Office\Office12\pptview.exe “%1”

After I remove assoc and ftype for .pps (in user-B space) per article, by doing
assoc .pps=(blank)
ftype .PowerPointViewer.Slideshow.11=(blank)

"Control panel / default program" still shows the wrong programs associated to .pps; I expect to see no association.

Any help will be greatly appreciated.

While in the UserB desktop, click on Start and All Programs. Does the PowerPointViewer show up there? If it does not, then that is your problem.

When installing programs, sometimes they will install for all users without asking, sometimes they will ask if you want to install for all users, and sometimes they will not ask and just install in the current user's desktop. That means they must be installed separately for each user.
