An error -5003 has occurred while running the setup

[zelenak]

I just bought Home Designer 7.0, and when trying to install it, the InstallShield Wizard makes it to 2 bars then gives me an error message:

"An error (-5003: 0x8004ace8) has occurred while running the setup.

Please make sure you have finished any previous setup and closed other applications. If the error still occurs, please contact your vendor: Chief Architect Inc."

Customer Support is closed for the night, so I was curious if anyone had any tips for the time being. I've closed all my apps, gone through the troubleshooting from the support site, restarted my comp... what else could make it work?

Thanks in advance.
