OPC UA in WINDOWS 10

[ponsdaniel]

Hello
Good,
I am testing the example in lazarus to connect to an OPC UA server using the libopen62541.dll library.

The source code is an example that I have found on the net, that other forums have answered working on linux.

Here in windows I can't find the problem because it is not working for me.

I have placed the library in the executable folder, I have placed a path in another folder where the library is.

But I always get the error.

Who can help me?

Without any knowledge from me about libopen62541.dll I can tell that this problem usually occurs when the bitness of the compiler and the library do not match (32-bit vs 64-bit) or that the library depends on the presence of other libraries (and those other libraries are currently missing).
