The installation procedure is slightly different depending on the version of Director and platform used. Make sure you have administrative rights to create files in the directory where Director is installed on your system.

Important: please remember that WebXtra sprites do not spawn a working web browser on the Macintosh: the Xtra is only fully functional on Windows. The Macintosh versions of the Xtra are provided as stubs to help users that must author cross-platform movies on the Mac platform, or need to work in both platforms with the same set of files and cast libraries, without any error messages. With these stub Xtras it is perfectly possible to write a complete application using WebXtra on the Mac and cross publish it for Windows using Director MX 2004.
