You say this ... "For example, on a single machine you can have the 32-bit version of SAS Enterprise Guide and a 64-bit version of MS Office with the 64-bit SAS Add-In for Microsoft Office."

And I say "How?" ... we use response files for silent SAS installations, and there is no 'Bitness' option for the Addin response file, so basically it defaults to what bitness EG is installed, which is a huge problem for us using 64-bit Office.

If there is an option we can add to the response files to force a 64-bit install of the addin over a 32-bit EG then I'm all ears ....
