.NET-Error when invoke "tiepie_hw_init" from TIEPIE_HW_API

[CDietz]

Hi,

I'm using the follow software products:

• NI LabVIEW 2025 Q3 (64-bit)
• TiePie WinUSB driver 10.0.2 Windows 10 / 11, 64 bit (https://www.tiepie.com/en/download)
• TiePie .NET framework package "TiePie.Hardware" 1.4.0 (https://www.nuget.org/packages/TiePie.Hardware)

When I try to initialize the API with invoke node "tiepie_hw_init", I receive the follow .NET error:

"Invoke Node
Exception has been thrown by the target of an invocation.
The type initializer for 'TiePie.Hardware.API' threw an exception.
Stack Trace:
at TiePie.Hardware.API.tiepie_hw_init()
at InvokeStub_API.tiepie_hw_init(Object, Object, IntPtr*)
at System.Reflection.MethodBaseInvoker.InvokeWithNoArgs(Object obj, BindingFlags invokeAttr)
in TiePie.Hardware_DotNet_Init&Close.vi"

Details are shown in the attachment. Has anybody a tip, what's the reason of this? Thank you in advance

since tiepie_hw_init is black you should click on it. Then choose from the method list appropriately.
