SUP 2.0 Installation error

Hello Experts,

When i am trying to re-install SUP 2.0 in windows 7 64 bit, it generates an error

"The installation detects an existing installation of Sybase Messaging Server. Uninstall it before proceeding with Sybase Unwired Platform Installation."

I deleted Sybase Installation Folder.

I deleted all registry related to Sybase.

No any services found related to Sybase Messaging server.

Please reply me.

regards,

Tapan
