Hello everybody,
since 3 days I'm struggling with the following VISA error:
VISA or a code library required by VISA could not be located or loaded. This is usually due to a required driver not being installed on the system. (-1073807202)
I've connected a frequency synthesizer via USB cable to my PC with LabView (2017, 64bit) installed. I also tried with a fiber thermometer. Communication had already been established with NI MAX to both devices as I could write and read commands with the testpanel.
When trying to communicate in LabVIEW with very basic "from scratch" programming with simple VISA elements (VISA configure serial port etc.), I keep on getting the mentioned error code at the Configure Serial Port function. I already reinstalled LabVIEW and force reinstalled NI VISA 17.5. The problem keeps reappearing though.
Do you have any more ideas what might be the problem?
Attached, I added a VI and the screenshots of the block diagram and the front panel for the thermometer communication. Com Port 4 is indicated as the device's port by both the device manager and by NI MAX.
Thank you very much for your help, I hope I didn't forget any important information.
Best
