64Bits and 32Bits versions (SOLVED - Read the manual!)

I am currently evaluating Padlock using W8.1 64Bits and Office 2013 64Bits. Downloade the 64Bits version of Padlock and installed. Developed a simple VBA application to test PadLock. Error msg that I need a 32 bit version of Excel. Can you please explain what do I need to do to test the padlock?
