For me it's a little more complicated because I want to allow to
install more than 1 version of the same application at the same time.
On the second go the install folder is created and the bin folder is
created inside that but no the installer ends quickly and nothing gets
installed on the second go. I then uninstall the newly installed
project and the next install will actually install files.
