Help New Computer Can't Load Corel X3

Good morning.  I received a new laptop and am in the process of reloading all my software on it.  Everything else loaded up perfectly EXCEPT Corel.

 I do not receive an error during loading.  It appears to load perfectly, but when I attempt to launch the program, I receive the following message:

 Unable to Create DOM document.  Class not registered.  Verify that MSXML4 is installed.

I've uninstalled and reinstalled several times.  I tried to call customer support but they are closed on the weekend.  I'm stumped.  Could it be that the new laptop is somehow not compatible?
