Simply forget MGI Photo Suite and use a better (free) program which will run under (say) Windows 7:

Or, if you must have your ancient software, get a Windows 7 PC and install it using 'compatibility mode'. (The PC I'm using to type this has Windows 7 Pro on it but I'm still running Photoshop 6 on it, which is theoretically 'XP only', simply by using compatibility mode).
