Getting Excel Crash Error: The RPC Server Is Unavailable. (Exception From HRESULT: 0x800706BA)

Excel Application Scope throws error " The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)" .

Root Cause: This happens when the output workbook is not available for further processing during the process execution.


Troubleshoot:
In case of using Kill Process activity & killed the output instance workbook of Excel Application scope, then remove/comment out all the kill process activity and verify.

If the issue still persists, perform the following:

  • Screenshot of the error
  • Share
    • Sample XAML where the Robot runs into exception/failure
    • Execution logs from the Robot machine
    • Event viewer logs from the Robot machine.


Steps To Replicate :(Alternate)
  1. Take wb as output of Excel application scope
  2. Kill Excel inside same Excel scope or Kill Excel outside Excel scope
  3. Use same variable in another Excel application scope.
