Dear Stephen,

A. Are you selecting a diagram to publish or are trying to Export to Excel from the Welcome window (or Diagrams Tab)?

B. Could you please share the .bpm model that you are attempting to export and the exact steps and configuration for the Export wizard? We'll try to reproduce this incident.


1. Check if your current Excel installation has any issues. This can be reviewed by going to your control panel and repairing the installation.

2. Review if Excel has any add-ins, which may be affecting Excel instances being opened by a remote call.

This can be reviewed in your Excel options, in the Add-ins tab, by checking if by un-marking your current COM add-ins, the problem is solved.

We look forward to hearing from you.
