Restoring Root Password on MSI installation
To restore your root password, if you run YouTrack as Windows service, please follow these instructions:
Stop the service
Navigate C:/ProgramData/JetBrains/YouTrack/conf/youtrack.jvmoptions. If youtrack.jvmoptions file is missing simply create one by renaming config file example (youtrack.jvmoptions.dist).
Add -Djetbrains.charisma.restoreRootPassword=true option to the configuration file. Configuration file format is described in the file itself.
Run the service as usual
