Removed Software-Rescanned Machine-Software still shows

I removed a software package, deleted the folders, removed the reg key for the package, and checked the HKEY_LOCAL\...\Windows\Uninstall and it doesnt show up there either. But when I rescan the machine, not only does the history not reflect the removal of the software package, but it is still showing up in my scanned software as residing on the machine. Yes, I can just delete the software, but when I remove software from a workstation, shouldn't it be reflected by the next scan?
