How to get Java software installation log files?


If an error occurs during installation, the installer creates log files on your computer that include details about the error. Providing us with the log files from a failed installation will allow us to do a thorough analysis of the issue.

Note: We recommend you to delete all versions of Java from your system before proceeding. For more information see Java uninstaller tool
