The software hasn't been released with 64bit support. This means that there's no way to make it work in a 64bit system, unless you use virtualization to install Windows XP. For this purpose, you can use Virtualbox as it provides all the necessary features to have Windows XP up and running in the fastest time possible. Install Virtualbox then use the online guide which explains how to create a virtual machine to install Windows. After Windows has been installed, transfer the application to the virtual environment and it should work normally.
Note: Windows XP Install Disc is required in order to make this work.
