# Manual License Key Installation
Read Time: 1 minute(s)
The jBASE installer will automatically update the license keys during Express and Advanced mode install. If you need to change the keys, for example, to enter a permanent key instead of an evaluation key, or if you performed a Minimal install, you can use any text editor such as Notepad or vi to enter the keys in the system.properties file. Do not use jED or ED.
The system.properties file is located in the config directory under your jBASE installation directory. For example:
You should have either a Permanent system license key or an evaluation license key. You may also have a Multisession and/or Websession key. Each key must be added as a separate entry in the system.properties file. New keys should be added at the end of the file, after the jruntime.license line, which should be left in the file without modification. When the keys have been added, the last lines of the system.properties file will look something like this (comment lines starting with # can be added for clarity):
Permanent license example:
jruntime.license = qP2XhdjqbdbiqzvfDBgPisP3ITiDfhyT jruntime.deepthought=5uGDQT5vh1DkpvMfqI+Srq5WWing6aYC jruntime.multisession=5uGDQT5vh1DuSp2afBWAXO9RoGIr73gb
Evaluation license example:
jruntime.license = qP2XhdjqbdbiqzvfDBgPisP3ITiDfhyT # Expires on 31 March 2018 jruntime.eval=L7G3Jq52/AVD9I9E6LNAvhp2l43xKnRU
jruntime.license = qP2XhdjqbdbiqzvfDBgPisP3ITiDfhyT jruntime.deepthought=5uGDQT5vh1DkpvMfqI+Srq5WWing6aYC jruntime.websession=99TvRhZrzwXahzjI9/NuqTNRlro/g1xpC/MJglgPQDE=
# jBASE 5.8 onwards
In the jBASE 5.8 releases and later, the jBASE licenses are located in %JBCGLOBALDIR%\config\jbase_config.json on Windows and $JBCGLOBALDIR//config//jbase_config.json on UNIX. The jlicenseupdate utility can be used to install these keys.
