Will sitebuilder 4.5x run on Plesk 11?

[Cnote]

I just recently upgraded my server to accommodate my billing software. I'm now running Plesk panel 11 on CentOS 6.3 final. I need to install sitebuilder on this new server so my clients can continue to manage their websites. I have a license for 100 domain on one server.

Please point me in the right direction to accomplish this.

Many thanks
