Hello everyone,

I'm trying to create an executable that uses gRPC library. The project works well from development environment but I get an error 7 when running compiled code:

Error 7 occurred at Call Library Function Node in grpc-lvsupport-release.lvlib:Create Client.vi:560002->Voluson_client.lvlib:Create Client.vi:560001->gRPCFunctionCall.vi->Sequence Editor 1.vi

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.

I tracked it down to "GetServerDLL.vi", which, by default, e.g. when not in run-time, runs the following code:


and returns path "C:\Program Files\National Instruments\LabVIEW 2023\vi.lib\gRPC\LabVIEW gRPC Library\Libraries\Win64\labview_grpc_server.dll", which is where the "Libraries" folder is located.

At run time, it executes this:


which, of course returns location of the exe+Libraries\Win64...

I'm not clear on the intention of this or what steps should I take to make it work? Do I need to copy the whole "Libraries" to the same location as the executable manually and then add it to build specs for installer?

Thank you for reading.
