myDAQ device will light up blue briefly then turn off once plugged into my laptop running on Windows 7 OS. Also I have been getting multiple installation errors when trying to install te myDAQ suite such as "NIDAQmx switch core 2.2.0. has failed to install" NI PXI Platform services 2.6.2. has failed to install" I have tried to reinstall the myDAQ suite dvd that came with my device as well as downloading the most recent drivers, but this still gives me the same warnings. What could be going wrong and what should I do to fix it?
Try a fresh installation, follow this guide and reinstall form the dvds. I would recommend to copy the files to the hard drive and run the exe file from there.
The blue light should stay on, like mentioned at the user guide. Take a look at the device manager and search for yellow question or exclamation marks. try to follow this recommendations or simply delete the entry and reboot. That should force windows to recognize the device again, when the software is ok. Good luck.
