Instal/Uninstall Problem

Sorry if this is a double post, I realized I was't subscribed when I sent
the first email.

Hoping Someone can give me a hand.

I had a developer who integrated the postgres msi into an installshield 10
installer. Somehow the uninstaller seemed to have half uninstalled it. All
the files are off the harddrive. When I go to add/remove programs it says no
installer package can be found. When I try to run the msi manually it says
the administrator has policies in effect to prevent this installation.

Im running XP Pro as administrator

Thanks in advance.
