Uninstalling PDW app in Windows Vista

[Rémi]

Hello.
I had a client install an Access app I built using Access XP and
package with the Package and Deployment Wizard onto his Windows Vista
laptop.

I've looked into this briefly, and I see that older installation
packages run under "virtualization" for Windows Vista - copies of the
files get placed in a user-specific folder, and if you use the
registry, you're only accessing a virtual copy of it.

I've found, though, that when uninstalling the Access application that
the "virtualized" copies don't seem to be removed. I find them under
"Desktop/[User]/AppData/Local/VirtualStore/Program Files/[Installation
Folder Name]". This wouldn't be a problem, except that when my users
install an update (also created with the PDW), the new virtual files
don't appear to overwrite the old ones, and when they run the
application, the old version still executes.

Asides from telling my users to delete the virtual copies, are there
steps that I can take to deal with this? Has anyone hit into this
yet? Or should I be going about doing this another way entirely?

Thanks,
Remi.
