TreeView is a phylogenetic tree viewing program written by Roderic D.M. Page.  
Previous versions of BioEdit included a distribution of the TreeView executable and 
supporting libraries in the apps folder.  At the request of the author full TreeView 
installation is now distributed with BioEdit.  This installation is contained within the file 
called TreeView.zip.

To install TreeView, unzip the file to a temporary directory, then run the program called 
"setup.exe" which will be created.  TreeView will install itself on your system.

Accessory Programs that generate a phylogenetic tree as final output (such as dnaml 
and protpars) are configured by default to open the output automatically in TreeView, 
provided that TreeView is installed into the default install directory.  If TreeView is
installed in a different directory, then accessory apps must be reconfigured to point
to the correct path.  For more information about this, see Help (from the BioEdit 
Help->Contents menu) and browse to "Basic Analysis Tools", "External Accessories", 
"Adding and Configuring External Applications".
