Download the file win.xpl from the PSX download section.  Copy it to the following subdirectory of your main X-Plane installation:

(Your X-Plane Directory)/Resources/plugins/XView/64

 

Note  It appears that the website software won't let me upload two versions of the file with the same name.  Please change the file name to win.xpl when installing it in your X-Plane directory.

 

Version of XView was compiled on MS Visual Studio 2015.  You need to have the corresponding redistributable package installed for it to work.  Get it here:
