This error can occur if the 32-bit version of Microsoft Office was not fully uninstalled before upgrading to the 64-bit version. Incomplete or failed installation tasks may leave behind unnecessary files, folders, and Registry keys, which can cause issues with Microsoft Office functionality and its integrations.

To resolve this error, we recommend contacting your IT consultant to perform a complete removal of Microsoft 365. Microsoft provides tools for IT professionals to remove any residual registry keys or files from previous installations. Afterwards, Microsoft 365 can be reinstalled from their website.

After Microsoft 365 has been reinstalled, you can return to LEAP and Create PDF once again.
