Java for Windows

A Java runtime environment must be installed before installing jLog. The newest Java 1.6 is strongly recommended for any version.
jLog V 5 requires Java 1.6 or newer.

Frequent upgrades to the newest revision is recommended as this usually provides both visual and performance improvements as well as bug-fixes.

Please note that you must install Java as a user with Administrator privileges.

Download JRE

The latest Java 1.8.0_92 ("Java 8") can be downloaded here (7 - 18 Mb).

Select the Java Runtime Environment (JRE) variant (unless you are a professional needing the extra functionality of the JDK for other purposes). It will install into C:\Program Files\Java when default values are specified.

Note: If you run a 64-bit Windows, you must install both the 32-bits and 64-bits versions of Java.

Change Java version for jLog V 4.x

You need to modify the jLog startup file after having installed a new Java version unless you are making a full install of the jLog application afterwards.

To change manually, locate the file 'conf/jLog.lax' where you installed the jLog application, i.e. typically C:\Program Files\jLog\conf\jLog.lax. Open it with a text editor and scroll down to find the entry:

# LAX.NL.CURRENT.VM

# -----------------

# the VM to use for the next launch

lax.nl.current.vm=C:\\Program Files\\Java\\jre6\\bin\\java.exe

You may place a comment sign in front of the current entry and append a new entry for the newest JRE:

#lax.nl.current.vm=C:\\Program Files\\Java\\jre1.5.0_09\\bin\\java.exe
lax.nl.current.vm=C:\\Program Files\\Java\\jre6\\bin\\java.exe

Save the file and restart jLog.
