I have the latest Java software installed on my computer, but I still don't see the Java logo applet on the download page. Why not?
If you know that you have Java software on your computer,
but you still cannot see the Java logo
applet, you should check to see whether your browser is configured to use
the Java platform or not.
To do that, first open the control panel.
From the Start menu, select Settings, then Control Panel to open
the Control Panel. You should see a Java coffee-cup icon
in the Control Panel. (If you don't, it probably means the latest
version of the Java platform isn't installed on your computer.)
Double click on the icon to open the Java Control Panel. In the
Java Control Panel, click on the Browser tab and make sure that
the Microsoft Internet Explorer box is checked. If it is not
checked, click the checkbox to select Microsoft Internet Explorer,
and then click the Apply button. Restart the Internet
Explorer browser and try viewing the Java logo applet again.

How do I know whether the latest version of Java software is installed on my
computer?
The easiest way to determine whether the latest Java software is installed
on your computer is to point your browser to the
Java software web site and click to download. If you do not have the latest
version of Java software, it will be automatically downloaded onto your
system.
- I changed my browser setting while Java Plug-in Software was running, but it still uses the old settings after the change. Why?
The browser settings are read in by Java Plug-in Software when it is started. These settings are valid throughout the lifetime of the browser session. To make Java Plug-in Software read in the new settings, simply restart your browser. If you are running Active Desktop with Java Plug-in Software, you need to restart the machine.

When trying to play one of the online games at pogo.com, I get an error message that says "Java corrupt or misinstalled." What can I do about it?
The pogo.com web site will display this warning message if one of the online games takes too long to load onto your computer. The message about a corrupt Java installation will be displayed even if there is nothing wrong with the Java installation, and the long load time is due to a slow internet connection on your computer.
If you see this message, try some of the other games on the site to see if you can run them. If you can, that's a good indication there's nothing wrong with your Java platform installation. Try your game again when the pogo.com response time or connection might be faster.
- Is Java software and Java Plug-in product the same thing as JavaScript?
No, JavaScript is an entirely different technology and it is not associated with the Java platform. For more information about JavaScript, see the Netscape DevEdge website.

I would like to develop programs for the Java platform. How can I get started?
The following sites are useful for new developers (and for experienced developers too!).
If you're a Visual Basic developer and want to add the Java programming
language to your coding repertoire, see the Java 2 Platform
Resource Center for Visual Basic Developers.

Additional troubleshooting tips are available on the Java platform's
Installation Notes page, and the
Troubleshooting FAQ.

How do I know whether Java software has
been installed on my computer?
If you use Microsoft Windows and the Internet Explorer browser, the easiest way to determine whether Java software is installed on your computer is to point your browser to the Java software web site and click
to download. If Java software is already installed on your computer, a Java coffee-cup logo will appear on that page. If it is not already installed, you'll be prompted to download the latest version from the same site.
If you use Microsoft Windows but not the Internet Explorer browser, go
to the Microsoft Windows Start menu, select Settings, then Control Panel. If the Control Panel contains a Java coffee-cup icon, then Java software is installed on your computer.

When downloading or installing the Java platform, I get a message that says "We recommend that you do not install this Java Platform for the following reasons." What's going on?
The Java technology installer checks your computer to ensure that your
operating system is configured for optimal use of the Java platform.
The installer displays a message if it detects anything that's not
optimal and suggests actions you can take to configure your computer
for best use of the Java platform.
An example: The Java platform performs best on Windows 2000 if
Windows 2000 Service Pack 2 from Microsoft is installed. If the
Java platform installer determines that your computer uses Windows 2000
but doesn't have Service Pack 2, it will display a message that says
"The Java Platform does not support the operating system service pack
on this machine. Please upgrade to service pack 2 from the Microsoft
web site. Continue anyway?" You can download service packs from
the Microsoft web site.
In all cases, you are given the option to proceed with the installation
if you want to, regardless of the warning. There is no harm in installing
the Java platform even if you see one of these warnings. The warnings are
there just to let you know that you might encounter a situation
in which some programs don't run properly.
- After I complete the autodownload process, I got
the message "Can't run 16-bit Windows program." What's wrong?
This message may be caused by an unsuccessful download. Retry the
autodownload from Java software or download manually from the Java 2 Platform, Standard Edition page.
- When the installer is launched, it complains about insufficient disk space on C:. What should I do?
The installer requires about 20 megabytes of free disk space to expand itself in order to complete the installation. You should delete unneeded files from your C drive to create sufficient free space for the installation.
- How do I uninstall the Java software from my system?
To uninstall the Java software from your system, use the Add/Remove Programs utility in the Microsoft Windows Control Panel.
From the Start menu, select Settings and then Control Panel to open the Control Panel. In the Control Panel, you will see an icon for the Add/Remove Programs utility. Double-click the icon to launch the utility. The utility will display a list of software on your system, including any Java software-related products that are on your computer. Select any that you want to install by clicking on
it, and then click the Add/Remove button.
