[FAQ] MS Office Plugin Compatibility: 32-bit to 64-bit Migration

Applies to: MS Office Excel, Outlook, PowerPoint, Word Connectors


Will the io.Connect adapter work after migrating from 32-bit to 64-bit Office?

Yes. The adapter will continue to work seamlessly after migrating from 32-bit Office to 64-bit Office.

How does the installer handle the migration?

The io.Connect installer automatically detects the Office bitness on your system and installs the appropriate adapter version accordingly.

E.g. for Excel, you will see two files:

  • GlueXL.xll — 32-bit add-in
  • GlueXL64.xll — 64-bit add-in

The installer installs only the version matching your Office bitness and no manual intervention is required. The same automatic detection and installation logic applies to add-ins for Outlook, PowerPoint, and Word.
