Upgrading to Windows 10 and getting old VIs to run

Highlighted

Hi,

I had LabVIEW 2013 on Windows 7. After upgrading to Windows 10, the existing LabVIEW version was unable to find any device. Thinking that this could be a too old LabVIEW version for Windows 10, I had LabVIEW 2018 installed. When running the VI, it gave an error saying that DAQmx cannot be found. I tried installing DAQmx but that gave an error as well. I then tried LabVIEW 2015, which gave the same error when running the VI.

Unfortunately, the computer ran into blue screen error while installing DAQmx and Visa drivers. It doesn't allow me to enter safe mode even when boot options are changed. Does someone know what's going on? Any help would be much appreciated.

I don't quite understand your problem.  If you have a working PC running Windows 10, you should have only the "usual" amount of trouble installing an appropriate version of LabVIEW (for Windows 10, you should restrict yourself to LabVIEW 2016 or later).

 

You need, of course, a license appropriate for whatever Version you install.  With a license, you should be able to go to the NI Website, download an Installer (probably NIPM, which has gotten better at its job), and start installing LabVIEW.  I suggest you install only LabVIEW (and I suggest you install 32-bit LabVIEW), no Drivers, and few Add-Ons (deselect everything and then install only what you think you'll use), then reboot.  Next, install DAQmx and just the drivers you'll use (which probably does not include the 488.2 Driver).  Activate and you should be good to go.  If there's still something you need, just install it, but don't "install everything".

P.S. -- if you have a "partial" NI installation and are having trouble adding to it, I'd suggest uninstalling all NI software and starting over.  Instructions how to do a safe uninstall can be found on the Web and in this Forum.

What version of DAQmx did you install?  If using LabVIEW 2018, you need DAQmx 18.0 or newer (in theory through 22.X).  Personally, I would install LabVIEW 2019 SP1 with DAQmx 20.0 (current version): this is my current setup.

My computer ran into blue screen error while trying to install the drivers. Once that was solved, uninstalling existing versions of LabVIEW didn't work as well. Finally, we had to reinstall Windows 10, remove the DAQ card and do the following in order: install LabVIEW (2018 sp1), install DAQmx 18.0 drivers, plug in DAQ card with cable and Install VISA drivers, following a reboot at each step. It's working now. Thanks for the help!

If you have a DAQ  card, the next question is which model and which DAQmx versions support it. That can limit which DAQmx versions (and thus which LV version) you practically have available. It seems you got it to work, but it can be good to know.

In general you Always need to install DAQ after a LV install and atleast until the last versions, LV needed to be installed from older to newer.
