Anybody know how you can programatically install a .mxp file in a Mac.
OpenWithApp does not appear to be working.

For example:
dreamweaver.openWithApp("file ///Macintosh HD/Applications/Macromedia
Dreamweaver 8/Configuration/Myapp/Myapp.mxp","file ///Macintosh
HD/Applications/Adobe Extension Manager/Extensions Manager.app");

Does NOT work.
