Uninstalling previous versions of Corel Draw

I have bought Corel Draw X3 and had Corel Draw 9 and 10 installed on my PC. I thought it best to uninstall the older versions, but during the uninstall process, I got a message "MSI failure has occured" "Msinstall Product error 1603. The it finishes and Corel 10 is still showing in my ADD/Remove in Control Panel.

I have signed up at this site and searched for the error message, or help in uninstalling older versions of Corel Draw as well as searching Corel's Knowledge Base, but i can't find any references to uninstall problems.

Can anyone tell me how to uninstall Corel Draw 10 manually?


Thank you
