Hi Support Team,

after updating the server from 1.7.1.66 to 1.7.1.76 the dUnitX Action fails with the following message:

"An error occurred whilst attempting to run DUnitX Action. Exit code: 255. Error text: . "

I assume this has to do with the "\\server\share\n..." problem...

Best regards  
Michael

Hi Michael,  
  
Can you send us details of your DUnitX action settings, any recent errors in the event log,&nbsp;and the rest of the build log so we can see the command line parameters passed to DUnitX? &nbsp;The diagnostics report will provide the first two items.&nbsp;  
  
The action is working in our tests and I can’t see any recent code changes which would be relevant.&nbsp;
