How to check Java is installed on your PC
Your computer needs the Java Runtime Environment (JRE) version 1.4
or greater installed, in order to use software developed by iceKnife.
This page outlines simple instructions on how to check the
current state of Java readiness of your computer.
How to check if you have the Java 2 JRE
installed
- Instructions for all
computers:
- Open a command prompt window
- (For Windows users,
choose Start -> Run [Enter] then type
"cmd" [Enter])
- At the command prompt, type "java
-version" [Enter]
- If the result says on the first line "java
version "1.4.0"", or the same but with
higher numbers (i.e. "1.4.01",
"1.4.1"...), then you have a suitable
version of Java installed.
- However if the numbers are lower (i.e.
"1.3.x") or the result said something like
"'java' is not recognized as an internal
or external command, operable program or batch
file.", then you need to install a suitable
version of Java before installing any iceKnife
software.
Download the latest version of the Java Runtime
Environment for your computer from Sun Microsystems.
