Unable to install on new Toshiba Laptop using Windows 8

Hi - I have downloaded the software from Corel's site using the download link & serial numbers provided on the email confirming my purchase.  However application does not load.  The shortcut icon has a message saying "side-by-side configuration is incorrect".  I do not understand this.  Does this mean I am unable to use this software on my new computer?

I also installed Paint Shop Pro X2 in the same way with exactly the same problem.

Appreciate any help
