The libopenalprc binary was added in 2.4.0. We haven't compiled binaries for that release for Windows yet. You can compile it yourself following the guides, or you can pull an older version of the .NET integration which works with the older OpenALPR lib.

Hi matthill,
First of all thank you very much for sharing this project with us.
I'm also getting same error when i'm trying to run C# sample project. I couldn't find the required DLL(libopenalprc.dll). You mentioned that it can be found in 2.4.0 and you haven't compiled binaries for that release. But where is 2.4.0? I could find only 2.3.0 as the latest release. Please help me in this. Thanks in advance.

I am using Openalpr v2.8.1 and still can't import libopenalpr.dll. I know it exists in the base build directory but test.py is unable to run because I get the following error:

FileNotFoundError: Could not find module 'libopenalpr.dll' (or one of its dependencies). Try using the full path with constructor syntax.

I have added this directory to PATH and also tried using os.add_dll_directory(<path to the dll>) as suggested here

I have also read that the above error can arise because the libopenalpr.dll itself imports other dlls as mentioned here

I am using python 3.8.5 x64
