How to Find out Whether You Have 32-bit vs 64-bit OneNote
Like OneNote, Onetastic comes in two versions: 32-bit and 64-bit. You need to install the correct
version based on whether you are running 32-bit or 64-bit version of OneNote. Note that
even if you are running 64-bit version of Windows, you may still have 32-bit version of
OneNote.
