When the verbose MSI log (/L*vx) states that registration failed, is there another log that records details of the registration process?


  • Carbon Black Cloud Sensor: 3.5.x.x and Higher
  • Microsoft Windows: All Supported Versions


The cb-installer-<VersionNumber>.log file records details about the registration process, and it is located in one of the following directories
C:\Users\All Users\AppData\Local\Temp

Alternately search via cmd.exe
  1. Open cmd.exe
  2. Search for file in user's Temp directory
    cd /d c:\
    dir %TEMP%\cb-installer-*.log
  3. Search for file across file system if nothing found above
    dir /s %TEMP%\cb-installer-*.log

Additional Information

  • The text <VersionNumber> will vary based on the version of the installer being run (ex: cb-installer-, cb-installer-, etc.)
  • The precise location can typically be found by typing %temp% in the run box and pressing the Enter key
  • The location is usually determined by the user logged in at the time of the install attempt
  • The cb-installer-<VersionNumber>.log file also contains many useful details about installation of services so is worth reviewing for any install issues
