Hello, National Instruments does not currently offer or support products that are certified for use with 64-bit processors and corresponding Windows operating systems. Note that the 64-bit versions of Windows are not compatible with previous 32-bit Windows drivers. All National Instruments hardware drivers currently offered for Windows XP are based upon 32-bit technology and thus will not function on 64-bit Windows. If you have a strong desire to use National instruments hardware on 64-bit versions of Windows, consider one of the <a href="http://sine.ni.com/apps/we/nioc.vp?cid=11737&lang=US";>NI Driver Development Kits</a> or <a href="http://sine.ni.com/apps/we/nicc.call_me?p_action=country&p_lang_id=US";>contact your NI Sales Representative.</a>
Though all hardware and software products are not supported at this time in the 64-bit structure, the basic programming functionality of LabVIEW has been observed to passably function. Do you see a common reason for the LabVIEW crash? How often do you see the crash? Perhaps with more information we can grow to more effectively support the 64-bit operating systems. I hope this helps! Please let me know if there is anything else I can do. Liz F National Instruments
