To launch an executable without a project: Create a debugger project by opening
                    the executable as a project (File->Open Project) and entering the path to the executable
                    that you want to debug (ex: \\MyTestComputer\c$\MyTest.exe). Then open project properties
                    and change the Connection property. Also adjust the Executable property to the path
                    that the remote computer should use.
