Based on the information found on the developer's website, the software is compatible with the following Windows versions: Windows XP, Windows Vista 32-bit, Windows 7. There is nowhere mentioned about the 64bit version support.
The first thing to try is Compatibility. Right click the installation package and select Troubleshoot Compatibility, then follow the recommended settings.
Secondly, contact the developers because it's possible you'll need an upgrade to make the software compatible with the 64bit versions of Windows.
