I am using Windows 10 and have installed a 64 bit version of Office. I cannot for the best of my life remember having installed a 32 bit version as well. However, when I open the Start Menu, I find two Excel entries, one labeled just Excel, the other labeled Excel 2016.
When I open the Excel entry and use the VBA conditional compiler directive constants
Win64 to determine the bitness of Excel, I unexpectedly find that the Excel that I am running is a 32 Bit version. However, If I open the Excel 2016 entry, and determine the bitness of Excel, this time, I find it to be 64 bit.
Furthermore, when I try to find out the executed exe with a right mouse click on either the Excel or Excel 2016 entry, I am only presented with a Open file location on the Excel 2016 entry. The Excel entry seems to be missing this option.
I am very confused what's going on here and would appreciate any help for clearing this up to me.
As per harrymc's request, the first three lines of File > Account > About Excel in the 32 bit version read
