How to open and view .PK4 files

When you attempt to open a .PK4 file, your PC displays an error: "Windows can't open this file". This error is caused by two issues in the Windows system registry: 1) the PK4 file type registration is missing, and 2) the host application (or the file viewer) for .PK4 files isn't properly associated with its file type registration.
