How can you tell if a user is using a Microsoft Office 64 bit.  The reason 
why I am asking is because I am using a external program to external program 
that interfacing to the mail client.   In order to interface with a 64 bit 
mail client, I need to have a 64 bit version of the external program which 
is not cheap.    The last time this happen is took a while to figure out why 
is was not working.  Thus, I would like to display a message if the user is 
using a Microsoft Office 64 bit.

Thanks
Kevin

Kevin,

>How can you tell if a user is using a Microsoft Office 64 bit.

You can check the Windows Registry -- using something like Thomas Braun's 
Registry Class -- for the "Bitness" value of Outlook. The following keys are 
relevant, depending of the installed version of MS Office:

* Office 2010
  Registry Key: HKEY_LOCAL_MACHINE\Software\Microsoft\Office\14.0\Outlook

* Office 2013
  Registry Key: HKEY_LOCAL_MACHINE\Software\Microsoft\Office\15.0\Outlook

* Office 2016
  Registry Key: HKEY_LOCAL_MACHINE\Software\Microsoft\Office\16.0\Outlook

Check the "Bitness" value under this key. It will be either "x86" or "x64".

If the key (or value) doesn't exist, Outlook (or Office) isn't installed.
