Hi, Did you install Talend V 6.3? What's the error message you are getting? Is there any uninstaller.jar file which is located in <Talend>\Server\6.x\<TOS_MDM-Server-2016xxxx_xxxx-V6.x.x>\Uninstaller? Best regards Sabrina

Hi Sabrina, This problem has resolved, just run the install process again, and set the target dir to another, remove the original directory, the database file is not necessary to recover for me. Thanks for your reply~
