Hello,
I am trying to use NI Modbus Library in a LV project used in TestStand sequence. When LV Development System adapter is selected whole sequence runs correctly but when changed to Run-Time I am getting error:
"LabVIEW Cannot Convert the LabVIEW Project Version (21.0) to LabVIEW Runtime Engine Version (21.0). The project or one of its libraries is in an older version".
As soon as I delete Modbus Library from the project the error is no longer present.
Software versions:
TestStand 2020 32-bit
LV 2021 32-bit
NI Modbus Library 1.2.1.42 (I have also tried 1.2.0.41
Already tried:
Mass compile everything,
Deploying TestStand System,
Reinstalling Library,
Different PC,
Using Version Independent Runtime Engine (with this one error changes to
"LabVIEW: (Hex 0x7) File not found. The file might be in a different location or deleted. Use the command prompt or the file explorer to verify that the path is correct.
LabVIEW project 'LVproj.lvproj' has missing dependencies. Open the LabVIEW project in LabVIEW for more details.
I would appreciate any ideas on how to solve this issue.

How about mass-compiling the Modbus library?

Hi Santo13,
seemed to be a good idea, already tried that, unfortunately didn't help
