Bamboo won't start as a Windows Service and throws error code 1:


  • Bamboo Server / Data Center installed using the ZIP file rather than the .exe installers.
  • Reproducible on the 64-bit versions of Windows Server 2016 and Windows Server 2019 DC.
  • 64-bit JDK.


The following error is thrown when attempting to start the Bamboo service:

Windows could not start the Atlassian Bamboo Bamboo on Local Computer, for more information, review the system event log. if this is a non-Microsoft service, contact the service vendor and refer to service-specific error code 1.

Checking the Event Viewer, the respective log entry doesn't have much additional information and just shows "incorrect function":

The Atlassian Bamboo Bamboo service terminated with the following service-specific error: 
Incorrect function.

When starting Bamboo through the command line (start-bamboo.bat), you might see the following error in the console, although Bamboo successfully starts up:

Can't load IA 32-bit .dll on a AMD 64-bit platform] java.lang.UnsatisfiedLinkError: <BAMBOO_INSTALL>\bin\tcnative-1.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform


The ZIP version of Bamboo bundles a 32-bit version of the binaries, including Tomcat and its service wrapper, which is not fully compatible with a 64-bit system.


Use the 64-bit installer of Bamboo. You can run an "upgrade" to the exact same version using the installer.

Other things to check

  1. Upon any changes to the environment, please re-install the service.
  2. Check if the JDK being used is a 64-bit one, and if the JAVA_HOME variable is correctly set.
  3. Make sure to run the service using a Local User with full access to all Bamboo directories. See Running Bamboo as a Windows service as the local user.

Another option, although highly not recommended, is to use a 32-bit version of the JDK.
