I wasn't able to find any specific information about that particular error code. Often times errors during installations sometimes due to previous uninstallations that did not execute properly. That may or may not be the case with you.
There are some alternatives you could try to get the NI-SWITCH software installed, but if you're not actually using any hardware that requires NI-SWITCH, you might just not install it at all. I'm only assuming this might be the case with you because I believe the installer automatically installs it by default no matter what hardware you have. Look at the <a href="http://digital.ni.com/softlib.nsf/954feaeea92d90918625674b00658b83/1a578095a37aae8386256dd500782470?OpenDocument";>NI-SWITCH download page</a> for a list of products that require NI-SWITCH. If your hardware isn't listed, choose "custom installation" the next time you try the installer and deselect NI-SWITCH so the installer does not try to install it. Now, if your hardware really does need the NI-SWITCH software, try deselecting it anyway. Download and install NI-SWITCH separately from the link above and see if that changes things. I hope this helps! Russell Applications Engineer National Instruments http://www.ni.com/support
