Modified installation procedure.
Problem with installation was introduced by changes in latest Python XY. In this version it will no longer auto install ETS if the user just hits "next" during the installation process of Python XY. Furthermore there is DLL problem with the package "win32ui" requiring a specific version of the Microsoft Visual Studio C++ redistributable, not included with Python XY. We use exactly this package during the installation. This then causes Sundials/Assimulo to be skipped during the installation.
This modified installation batch file, now offers the user an automated installation of VCRedist, PythonXY and ETS. The required files are automatically downloaded as needed.
