When installing the WebEQ Viewer Control (referred to as the MathViewer in WebEQ 2.5 and earlier), some users find that when going to the Viewer Control test page, that the example equation "x² + 4x + 4 = 0" does not appear. This may occur for the following reasons:

Your browser does not support Java
Java or JavaScript is not enabled in your browser
Your browser that is not handled by our automatic installation
The automatic installation failed.

If you are using a Macintosh, please see our notice about installing the WebEQ Viewer Control on a Macintosh.

Reason

The WebEQ Viewer Control is a Java applet. Your browser must support Java and have it enabled in order to use the Viewer Control. The automatic WebEQ Viewer Control autoinstallation process requires that your browser supports JavaScript and that it is activated to work correctly. Some browsers, such as Opera, are not supported by our autoinstallation script and require manual installation. Automatic installation may fail if you are behind a firewall.

Solution

Make sure that you have Java installed on your computer. If you have Java installed in your browser, You should see, inside the box below, a message saying, "Java is installed and active in your browser".

If you do not, you will first need to refer to your browser's Help files or website to get instructions for installing and activating Java in your browser. Some browsers are distributed without Java and you must download it as a plug-in from Sun Microsystem's website.

Next, make sure that your browser supports JavaScript. Click here to test JavaScript . A message box should open that says, "JavaScript is active in your browser." If a message box doesn't open, you should refer to your browser's help files, online documentation, or support staff to see how to activate it. After activating JavaScript, you can return to our WebEQ Viewer Control Installation page and try automatically installing it again. If you cannot get the automatic installation to work, you will need to install the WebEQ Viewer Control manually.

This notice explains how to manually install the WebEQ Viewer Control for the following browsers:

1. Netscape 6.x, 7.0bx, Mozilla 0.9x and 1.x, and Internet Explorer 6.x with the Sun JVM

2. Microsoft Internet Explorer 4, 5, 5.5, and 6 with the Microsoft JVM

3. Netscape 4.7x

4. Opera 5 and 6

If you are using a configuration that is not addressed here, please contact us and include which operating system, browser, and versions of them that you are using.

Netscape 6.x, 7.0bx, Mozilla 0.9x and 1.x, and Internet Explorer 6.x+ with the Sun JVM

Netscape 6.x and Mozilla 0.9x use the Java Runtime Environment (JRE) provided as a plug-in by Sun Microsystems. It is also possible to download this plug-in and use it with Microsoft Internet Explorer. To view WebEQ equations, you just download WebEQApplet.jar and place it into the appropriate location in your JRE directory.

If you are using Netscape 6.x, download the file WebEQApplet.jar by right-clicking here and choosing "Save Link As…". The Save File dialog will open. If you are using Mozilla 0.9x, skip to step 4.
In the "Save in:" pull-down menu, select your Desktop.

Click the "Save" button. Skip to step 6.
In Mozilla 0.9x, click here. The "Enter name of file to save to…" dialog will open. Select your Desktop.

Click the "Save" button.
After the WebEQApplet.jar file has finished downloading to your Desktop, quit your browser.
The following applet will identify the version of Java you are running and locate where it is installed. You will need to place a copy of the WebEQApplet.jar file you have downloaded into the Java Home Directory.

Launch Windows Explorer via Start>Programs>Accessories>Windows Explorer or by choosing Start>Run and typing in explorer and clicking "OK". Windows Explorer will open.
Navigate to the location of your Java Home Directory and place a copy of WebEQApplet.jar into that folder.

Upon restarting your browser, you should be able to properly view equations created with WebEQ such as the one on our test page.

Microsoft Internet Explorer 5, 5.5, and 6 using the Microsoft JVM

To manually install the WebEQ Viewer Control, you need to download a self-extracting, zipped copy of the WebEQ Viewer Control files and expand them into the correct location. To determine the exact location for your computer, do the following,

Launch Windows Explorer, which should be accessible via Start>Programs>Accessories or by choose Start>Run and typing in explorer and clicking the Run button.
If you are using the Java environment provided by Microsoft, you should have one of the following locations:

C:\Windows\java\lib
C:\Winnt\java\lib
C:\Windows\java\trustlib
C:\Winnt\java\trustlib

If you downloaded and installed the Java Runtime Environment (JRE) provided as a plug-in for Internet Explorer 6 by Sun Microsystems, follow the instructions above for installing the WebEQ Viewer Control in Netscape 6.x and Mozilla 09.x.
Determine which of the above 4 possible locations above exists on your computer. If you have both the lib and trustlib locations, use the lib location.
Download the self-extracting zip file, WebEQApplet.exe, by clicking here. You should see the following dialog:

Choose "Save". The Save As dialog will open.

Use the "Save in:" pull-down menu to save the file on your Desktop for easy access. Click the "Save" button.
The window below will open to indicate your download progress.

Click the "Unzip" button. The WebEQ Viewer Control files will be unpacked into the location you specify. In order to view equations, the files must be unpacked in the correct location. When the processed is finished, you will see the dialog below:

Click "OK" to close the "WinZip Self-Extractor" window then the "Close" button to close the "WinZip Self-Extractor [WebEQApplet.exe]" window.

Upon restarting Microsoft Internet Explorer, you should be able to properly view equations created with WebEQ such as the one on our test page.

Netscape 4.7x

To manually install the Viewer Control, you need to download a copy of WebEQApplet.jar and place it into the correct location.

Download the file WebEQApplet.jar by right-clicking here and choosing "Save Link As…". The Save As dialog will open.
