What is the best way to download the form?

The best way to download the form is use your right mousebutton to click on the link and then to select "Save target as …" If you can't save the form in this way, then the form can be found at the location of your temporary internet files (consult the documentation of your browser or your system administrator for help). If this is the case and the browser is shut down, the form is thrown away and can no longer be opened.
