Problem with CorelDRAW X5 installer on Windows 7?

Hi,

I just purchased CorelDRAW GS X5 and can't get it to install on my Windows 7 Home Premium 64-bit system.

The download seems to go okay, but when I open the installer I immediately get an error:

I downloaded using both Firefox (get an error from the installer) and IE 8 (same error from the installer).

Is anyone else having luck installing?

 

Thanks,

Stephen
