Issue in reinstalling SUP 2.1 runtime

Hi,

Firstly, for uninstalling SUP 2.1 i ran silent unistaller.exe due to which i was unable to see SUP in Control Panel(add and remove programs).

When m trying to reinstall it,

it shows

*The installer detects existing installation of advantage database server and messaging server.

Uninstall them before installing SUP 2.1*
