We can't install Office 2013 64-bit on a Win 7 PC that had a 32-bit version of Office

[Ron in WC]

We have a development PC running Windows 7 64-bit. This PC has been around for a while, and way back had various 32-bit versions of Office installed, starting with Office 2003 through 2010. Those versions were uninstalled and Office 2013 Pro Plus 32-bit was the latest version installed. That version was uninstalled using Revo Uninstaller then the registry was cleaned using JV16 to make sure leftover junk from the prior 32 bit version(s) was removed so we could install Office 2013 x64 Pro Plus, which we now need for testing. It won't install because the installer sees something left over from the prior 32 bit version(s). We can't wipe the PC and start over; it has special sensor hardware and software that we can't move to a different PC and we're on a tight timeline. We searched the registry and the Program Files (x86) folder and subfolders for anything left over from Office without any luck. The error message reads:

We can't install the 64-bit version of Office because we found the following 32-bit
programs on your PC:


Please uninstall all 32-bit Office programs, then try reinstalling 64-bit Office.

Note that the error message doesn't list the name(s) of any "32-bit programs on your PC" in the error message.

Anybody have an idea how to force an installation of 64-bit Office 2013 Pro Plus?
