Can somebody help me fix my Installation Problem?

Every time I install my VB 6.0 Enterprise Edition this problem occurs.

I always finish the installation, but every time I start the VB 6.0, this annoying message box always appear saying "Preparing to Install..." the title of the message box is "Windows Installer" and the VB 6.0 will not continue to load unitl it hangs.

Waiting for your help if you experience this... THANKS!!!
