Christian, Since the launch of LabVIEW 7.1, we are not selling the App Builder 6.1 any more. We don't keep the old version CDs in stock. It is best to contact your regional sales rep to see what options there are. If you absolutely have to use this older version, you could maybe purchase the App Builder 7.1 and the sales rep could also send you the older copy. You can contact the sales department at Tel: (888) 280-7645 <A HREF ="https://sine.ni.com/apps/we/nicc.call_me?p_country=United+States&p_lang_id=US&p_form_id=6";>E-mail</a> sales Fax: 512-683-8411
