Zoho CRM Plug-in for Microsoft Outlook 64 Bit vs. 32 Bit

Zoho CRM Plug-in for Microsoft Outlook 64 Bit vs. 32 Bit

Using Windows 7 64 Bit with Outlook 2013.  When I download the plug-in I recieve message: "Lookslike you have downloaded the wrong exe. this 64 exe is not supported on your machine.  Would you like to downlthe right exe?".  I have a 64 bit system but I've played along and tried downloading the 32 bit exe but then I get the same message except it says "This 32 exe is not supported".  What gives?
