Please click on the
appropriate link below, read all of the
information carefully and follow the instructions as
appropriate.
Windows Users:
Blackboard now requires a new
Java Plug-in, J2SE Runtime Environment (JRE) 1.5.0_03
or higher (also known as JRE 5.0) in order to function
properly (effective 5/1/05). For
now, avoid installing Java 6 (1.6.x), because we are still researching
it's compatibility with our current Blackboard installation.
Note: Any prior version
of the Java Plug-in must be removed (if applicable) prior to installing JRE 5.0. Please read the
following instructions carefully and complete the appropriate procedures
as they apply to your computer.
Check your currently installed Java
Plug-in version:
1. To open the Java Plug-in Control Panel, do the following: In Windows
2000,
go to Start Menu -> Settings -> Control Panel
then
double-click the Java Plug-in.
In Windows XP, go to Start Menu ->
Control Panel
then double-click
the
Java Plug-in (XP users may also
have to click Other Control Panel
Options
in the left side of the
Control Panel
window to reveal the Java
Plug-in Control Panel link).
2. Go to the About tab and check to see what version
your Java Plug-in is.
3. Close the Java Plug-in Control Panel.
4. If you have a version of the Java Plug-in lower than J2SE Runtime Environment (JRE) 1.5.0_03
(JRE 5.0),
you may need to follow the "Uninstall..." and "Install
new..." instructions below for Blackboard to function properly.
Uninstall the current Java Plug-in by
doing the following:
1. Close all applications.
2. Go to Start Menu -> Settings -> Control Panel ->
Add/Remove Programs. (Note:
Windows XP users will go to Start Menu -> Control Panel ->
Add/Remove Programs.)
3. In the list of programs, choose "Java 2 Runtime
Environment" and follow the on screen prompts to remove the program.
4. If you have multiple installations of the "Java 2
Runtime Environment", you will need to follow the above steps for
each version that is installed.
5. Once you have completed the steps above, proceed to the
steps below under "Install new Java Plug-in JRE 5.0".
Install new Java Plug-in JRE 5.0:
1. Download and install the installer program for the
Windows version of the Java Plug-in which may be found at
http://java.sun.com/javase/downloads/index_jdk5.jsp - look for the item that is named something like "Java Runtime Environment
(JRE) 5.0 Update 12" (or higher), and described as "The J2SE Runtime
Environment (JRE) allows end-users to run Java applications"
(currently it is the 5th items down on the page).
For now, avoid installing Java 6 (1.6.x), because we are still
researching it's compatibility with our current Blackboard installation.
If this page isn't available, go to http://java.sun.com/j2se/index.jsp
and locate the newest Java 2 Platform, Standard Edition (J2SE) Java
Runtime Environment (JRE 5.0 family). If your operating system doesn't meet the
criteria for the latest version, you may have to try an older version of
Java 2 Platform, Standard Edition (J2SE) Java Runtime Environment (JRE),
but it may or may not work with Blackboard. Read important notes below:
- It is best to use Internet Explorer 6
(or higher) to download
the installer.
- Carefully follow the instructions
provided on the Java Plug-in web site.
- Depending on your download method and
the browser you use to download, you may need to run the installer after the download is complete. Make sure
you note the location where you save the installer on your computer if you
"Save" it rather than "Run" it, and
then launch it after the download is complete.
2.
Clear the JAR cache in the new Java Plug-in:
a.
To open the Java Plug-in Control Panel, do the following: In Windows
2000,

In Windows XP, go to Start Menu ->
Control Panel
then double-click
the
Java Plug-in (XP users may also

in the left side of the
Control Panel
window to reveal the Java
Plug-in Control Panel link).
b. Click "About" and check to
be sure you are looking at the
correct Java
Plug-in, the one you just installed, Java Plug-in J2SE
Runtime Environment (JRE) 1.5.0_xx. Click
"Close" to close
the
"About" window.
c. Click "Delete Files" under "Temporary
Internet Files", make sure all
boxes are selected and
