Note: Oracle purchased Sun, the creator of Java, in 2010 - references to 'Sun Java' should therefore be considered equivalent to 'Oracle Java' for the purposes of discussion.

Vuze (formerly known as Azureus) is a bit-torrent client which follows a similar format to eMule but its makers claim it can offer significant improvements in terms of hits, download times and navigating available material. There's no doubt that Vuze offers some spectacularly fast download times but this comes at a price. Mainly the fact that Vuze is extremely bloated and tries to install two.
Test Java[edit]
When encountering 'strange' problems with Vuze, the first thing to do is to check that Java itself works normally. Vuze is a Java program, which runs on top of a 'Java virtual machine' runtime program. You have either installed Java separately, or Vuze has installed it automatically for you.
If your Java works ok, you should see a summary of your java version.
Which Java version Vuze is using?[edit]
By using the 'Help / About Vuze' command in Vuze, you should see the current Java version as part of the short system summary text.
Example of the system summary:
Note: You can copy-paste that system summary text with mouse, so that it can be attached to a bug report or forum discussion.
Java installed by Vuze installer to non-regular place[edit]
If there was no Java installed in your computer when you installed Vuze, the Vuze installer (EXE4J) may install Java (Java Runtime environment 'JRE') for you. Depending on your operating system and its settings, the installed Java may end up at some non-regular place, and that may cause trouble later when you try to update Java.
For example, in Windows the installed Java JRE may be in
or in
If you notice that there is a Java JRE installed in such a place, you might consider deleting it and reinstalling the newest Oracle Java to the normal place.
Based on forum discussion, it may even be that the Oracle Java version checker checks the normal Java version, but does not notice the special Java installed by the Vuze installer. Evidence of that private Java JRE is e.g. if you see error messages with the string EXE4J_JAVA_HOME.
How to update to the latest Oracle Java version[edit]
Using an old Java version, or having more than one installed, may cause severe problems like 100% CPU usage! If you have installed Vuze but it is crashing or behaving strangely (eg. no windows display after the program launches) you possibly need to upgrade your Java.

Windows[edit]Installing Java[edit]
You must be running as an administrator to be able to install Java successfully. If your regular user account is a limited user (following the best practices for safe computing), you will need to temporarily switch the account to an administrative user in order to install Java successfully. After Java is installed on that account, you can switch that account back to a limited user account.
Java troubleshooting issues[edit]Outdated Java[edit]
You should update to the newest Java, either through the Java's built-in update checker (launched from Control Panel --> Java), or by the manual install process described below.
More than one Java installed[edit]
Oracle says that you are able to have multiple JRE versions installed, but in case you experience problems there, you might remove older versions.
Azureus.exe/Vuze.exe fails to launch with a 'could not create JVM' error[edit]
Alternative error messages: The JVM could not be started. The main method may have thrown an exception
This is often caused by one of two things
1) EXE4J (the Vuze launcher) is finding the wrong Java version
Open a command prompt and change directory into the directory containing the Vuze executable. By default this will be
or
Then set an environment variable to enable log file creation:
Finally run Vuze
This will create a log file starting with the name
in your temporary directory - to find this directory type

Check the log file to see if you can work out what went wrong
2) You have created a .vmoptions file with invalid entries (e.g. a VM memory size that is too large). There are two places that this can reside:
and
If you find a Azureus.exe.vmoptions file in any of these locations, delete them and see if that fixes it
Removing all versions[edit]
If you can't figure things out then the best approach is to manually delete all versions of Java and Vuze and re-install Vuze.
Java[edit]
Delete everything in the following folders (if they exist)
Vuze[edit]
Delete everything in
Mac OS X[edit]
Older (for Mac OS X 10.4.5 or later):
Configure Mac to use the correct Java[edit]
You should be able to change the preferred Java version *for applications* by using the Java Preferences utility. Make sure that Java 6 is the first in the list, before Java 5 or 4.
Linux[edit]
Most Linux variants include Oracle Java by default. It is also possible that there are additional java variants packaged in the Linux release.
To find out which version is installed in your system, run the command java -version.
The following instructions will help you install Java, e.g., if you got back 'command not found', or if you want to upgrade Java.
The following links lead to advice specific to different Linux variants.
