Microsoft Office 64 vs 32 bit

Most programs and plugins won’t work with Office 64 bit. You may have to remove the installed office 64 bit and install the compatible 32 bit version.

 

If you have installed Office 2013  including Microsoft Outlook 2013, Outlook sets a registry key named Bitness of type REG_SZ on the computer on which it is installed. The Bitness registry key indicates whether the Outlook 2013 installation is 32-bit or 64-bit.

 

Start, RUN, type regedit, go to the following key;

  • Registry path: HKEY_LOCAL_MACHINE\Software\Microsoft\Office\15.0\Outlook
  • Registry key: Bitness
  • Value: either x86 or x64.
  • X86 stands for 32-bit version.
