o2cPlayer.ocx supports the stand-alone o2c Player and embedded o2c objects in Microsoft Internet Explorer.
npo2cPlayer.dll supports the plug-in for either Mozilla Firefox or Netscape Navigator. For Firefox, npo2cPlayer.dll is located in \Documents and Settings\<user>\Application Data\Mozilla\Firefox\Profiles... and \Documents and Settings\<user>\Application Data\Netscape\Navigator\Profiles... for Netscape. The plug-in for Firefox and Netscape does not support Raytracing. However, you can retain o2cPlayer.ocx version 1.9.9.149 for the stand-alone player, Internet Explorer, and DataCAD independently from Firefox and Netscape.
The o2c Player plug-in is not currently supported by either Opera Browser or Apple Safari. The stand-alone o2c Player requires Microsoft Windows and does not currently support Macintosh operating systems.
