I have problem when try to close all the PXI channels by calling "niSwitch Disconnect All Channels.vi" and get error -1074130544. Can anyone let me know how to fix this please? I'm using Labview 2009 with "niswitch version 4.0.1"

Hi Triple H,
The error you are getting is generally returned when there is an issue with the instrument handle coming in. You can try tracing back the instrument handle and insure that all of the calls to the PXI device are called in the correct order. If you would like, you can post a screen shot of your block diagram to this forum and we may be able to see what could be causing the invalid session error.
