Tableau Server 2018.2 Install Fails When Using a Domain Account Starting With the Letter U for the Run As Service Account

When installing Tableau Server 2018.2.0 on Windows, starting Tableau Services Manager (TSM) does not succeed. Setup displays this error:
"WARNING: The server may not have started properly. Part of the installer exited with error code: (10). Check the logs: C:\ProgramData\Tableau\Tableau Server\logs\app-install.log for more information."
Look for the message 'Malformed \uxxxx encoding' in the app-install.log to confirm the issue.


  • Tableau Server 2018.2.0 and 2018.2.1
  • Windows


Option 1

Upgrade to Tableau Server 2018.2.2 or later. For more information, see Upgrade Tableau Server Overview.

Option 2

The following workaround will resolve the issue: 
Use a service account which starts with a letter other than U.


This behavior is caused by a known issue, ID 807662, which causes Setup to improperly interpret the "\u" portion of the domain\username as a Unicode escape. The issue has been corrected in Tableau Server 2018.2.2 and later.
