This is an install.js file that does the following --
1. Installs to the current browser that is invoking the installation
2. Additionally installs to a secondary location on the Windows desktop,
in this case C:\WINNT\System32\MyPlugin\
3. Writes registry keys exposing the above secondary install location for
other browsers to find. The keys are written according to the specification:
http://mozilla.org/projects/plugins/first-install-problem.html and follows the
PLID specification: http://mozilla.org/projects/plugins/plugin-identifier.html
