Dear user, the installer.bat is created as a last step for each region processing. It must be created for the particular region after all other processing steps are finished.
In the near future I am not able to come with a new version. I am too busy to achieve this soon. As a maximum, hopefully I will be able to upgrade used tools to recent versions, but this will not speed up processing or change current functionality significantly.
Of course, you or anybody else can clone the repository and continue development. If significant improvements will be achieved, it will be my great pleasure to include changes (together with author's credentials, of course) into the main development branch.
