Not to rain on your parade my friend but that software works for x86 and is considered by the developers to be obsolete and outdated, Resplendence however have created some nice free utilities, several are however a bit dated. Checkout this link to see that this program is no longer considered current: http://www.resplendence.com/downloads_obsolete.htm
As an alternative however allow me to provide a list of potential alternate programs from which you or others might chose that which suits there needs best, all are either open-source or free and designed to run on the Windows platform, as for x86 and x64 compatibility that I will leave up to the person choosing from the list what best suits there needs.
