Java Help Center

Welcome to the Java.com Help Center, which describes solutions for issues you might encounter when downloading and installing Java on your system. Each month, consumers request millions of Java downloads from our site.

As users install Java for diverse third-party applications and applets across different platforms, we track the most frequently reported issues and error codes that they send us. Find their corresponding answers and line-by-line technical instructions by using the Help Resources and FAQs menu. You can also narrow your search further by selecting the Platform and Java Version filter options with the drop-down menus.

• 'Can I remove the older versions and do I need multiple versions of Java installed on my system?'
• 'Error: You are located in an embargoed country and cannot download Java'
• 'What is JavaScript and how is it different from Java Technology?'
• 'Is javaw.exe infected with the W32/Trojan3.UJ virus?'

Terminology: Java is the general term used to denote the software and its components, which include 'Java Runtime Environment' (JRE), and 'Java Virtual Machine' (JVM). When error messages specifically include terms such as JRE and JVM, we retain them.

Versions: The Help section contains information on three versions of Java.
