Thanks for the assistance Gents- apparently it is the cvirt.dll causing the issue (CVI Runtime cvirt.dll was deprecated in 2017) KB article in case it helps anyone else in the future CVIRT.dll Is Missing From LabWindows™/CVI™ - NI. Copying cvirt.dll to c:\windows\system32 AND c:\windows\sysWOW64 fixed the issue.

ShaunR- thank you for your response. I'm using LV2018 32bit to attempt to get this old stuff working so the bitness should be OK. I used "Depenency Walker" as you suggested and while I'm sure I don't understand everything it shows it appears that there are a bunch of missing dependencies so it looks like there is an issue with the driver installer. Appreciate the help-

All, I need to get a VI with some Old Tabor Drivers working. I have installed the particular drivers from NI.com but I am getting an error stating a .dll cannot be loaded. If I open the Call Library Function Node it is expecting the .dll to be at C:\VXIPNP\WinNT\Bin\ww257x_32.dll . Since this location does not exist for Windows 10, I tried creating that folder and putting the .dll there and that did not work. I tried pointing to other locations as well and still no luck. Does anyone more familiar with how .dlls should work have an pointers (no pun intended) for how to get this garbage working? a

Good luck Sir- you are one of the shining lights of LabVIEW and your willingness to share deep insights on this and the NI forums was of immeasurable value. I hope that there are others at NI with a comparable understanding and skillset but that is probably unlikely.
