Your include path contains only "c:\programme\php\includes". It is missing the current directory ".". Thus PHP is not looking in the current directory for the file to be included.
Find the line for the include path in your php.ini and change it to:
include_path = ".;c:\programme\php\includes"
i.e. put the current directory in the include path list (notice the "." for the "current directory, and the ";" as a separator of the directories in the list).
