Browser throws error after Word launches and merge is complete



Developer is using the out of the box (OOTB) Word merge feature. Word launches fine and and the merge operation succeeds, but the browser raises an error.

Error Messages

There was a problem launching PRPC Word Editor

Steps to Reproduce

Use Word merge based on OOTB section @baseclass.WordMerge in a flow action.  

Root Cause

This problem occurs due to a very slow Word application launch on the developer's worstation.
The ActiveX based implementation allows 15 seconds for Word merge launch and respond back to the browser with a "successful launch" message. If the browser does not receive the message in the 15 second timeframe the reported error is raised.


Use an alternate Silverlight-based approach by installing HFix-7187.
The hotfix allows 24 seconds for synchronization between browser and Word, which is sufficient for the local environment.
