[Missing Files in the Code] While Creating a installer file - MissionInstaller.exe is missing from the Msi folder

#### Issue details
I have made some changes in the code of the Mission Planner, and now I want to make an exe or a installer file of it. I found these steps in the community forum - "
Setup Wix toolset (https://github.com/wixtoolset/wix3/releases/tag/wix3112rtm)
Build a release version of MissionPlanner and Plugins
Build the WIX project from the MissionPlanner solution, it outputs to the msi folder
go to the msi folder
run installer.bat
open create.bat and edit to match your settings and tool locations, delete the section which supposed to copy packages to the distribution servers.
run create.bat"

In the Msi Folder, I have the installer.bat and when I run it, it throws an error saying MissionPlanner.exe is missing, and I cant seems to figure out how to get that file into the project, how do i generate it, also there is no create.bat in my Msi Folder.

This is how my Msi Folder looks -
and this is a sub folder in the same directory -

Somebody please help.

Start with the WIX project in the MissionPlanner solution and the installer.bat file in the Msi folder, following the build steps described in the issue. Check where the release output is expected to be placed and whether create.bat is present in the current checkout. Done means the documented build flow produces the expected installer files without the missing MissionPlanner.exe error.
