Download and Install the Cosmo Player VRML Plugin
The Cosmo Player VRML plugin was NOT developed at NIST, only the 'new' installer from 2005 described below. As new versions of web browsers are released it is getting more difficult to install and run Cosmo Player, a plugin that has not been updated since 1998.
The instructions below are provided as a service to the VRML community. No support for Cosmo Player is available.
What is VRML?
Download Cosmo Player
Two different installation programs are available for the Cosmo Player VRML plugin for Windows. The installation programs work with any version of Windows including 8, 7, Vista, and XP.
After the plugin has been installed, use the VRML Plugin Detector to check if it works. The web browser should be restarted before trying to detect a newly installed plugin.
Installing in Chrome
If a VRML plugin is already installed in Firefox or Internet Explorer, then when Chrome is installed, the VRML plugin might be available in those web browsers as well. Similarly, after installing Cosmo Player in Firefox, it might show up in Chrome.
The original installer should work with Chrome, but the new one does not.
The Cosmo Player plugin might be blocked indicated by a small red X to the right of the search/navigation toolbar. Click on the X to manage plugin blocking.
Firefox 21 and greater
If you already had Cosmo Player installed in Firefox and upgraded to version 21 or greater and Cosmo Player no longer works, then follow these instructions.
Using Cosmo Player in some web browsers might require using the OpenGL renderer. See the instructions below to set the renderer in the Cosmo Player plugin.

New Cosmo Player Installation Program for Internet Explorer, Firefox, and Opera

Due to changes to Firefox 21 and greater, the new installer does not work without some fixes. See step 6 below.
The new installer does not work with Chrome however, if a VRML plugin is already installed in Firefox or Internet Explorer, then when Chrome is installed, the VRML plugin should be available in those web browsers.
