Hi
If you remove a software, it is possible it did not uninstall itself properly from the machine, eg it may have left registry entries. In this case, it is possible that systemhound will still report it as being installed.
If this is the case, then deleting the database will not solve the problem. (It is possible to delete the db, see this topic:
http://www.systemhound.net/community/index.php/topic,143.0.htmlSo can you tell me which software is being uninstalled, and do a check in the registry on that machine in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall to see if its still there.
