Is SmartClient compatible with the 64-bit edition of Microsoft Excel?

SmartClient is fully compatible with the stand-alone version of Microsoft Excel 2010 32-bit edition, but there are things to consider to make it work for the 64-bit edition. For SmartClient to be compatible with Microsoft Excel 64-bit, it is required that Microsoft Outlook 64-bit is also installed in order for it to detect that a 64-bit edition of Microsoft Excel is installed rather than a 32-bit edition.

A workaround to install SmartClient on Microsoft Excel 64-bit without installing Microsoft Outlook 64-bit is to manually edit the registry that is supposed to be created when Microsoft Outlook 64-bit is installed.

Please contact Celigo Support for further details on how to apply this workaround.

If you have installed Office 2010 including Microsoft Outlook 2010, 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 2010 installation is 32-bit or 64-bit. This may be useful to administrators who are interested in auditing computers to determine the installed versions of Office 2010 in their organization.

  • Registry path: HKEY_LOCAL_MACHINE\Software\Microsoft\Office\14.0\Outlook
  • If you have installed Office 2013 then use this Registry path:HKEY_LOCAL_MACHINE\Software\Microsoft\Office\15.0\Outlook
  • Registry key: Bitness
  • Value: either x86 or x64
