Britannica Ready Reference
You may need to delete certain
keys from your registry. The Britannica program cannot overwrite
a more recent version of the Java Runtime Environment (JRE)
on your system. This makes it impossible for the Sun JRE 1.3.1
to be installed on your computer if you have a newer version
of the JRE or if your version has been corrupted. However, deleting
the registry keys related to the Sun JRE before installing the
Britannica program seems to correct the matter. First, you will
need to use Add\Remove Programs to remove the Sun JRE.
