Use the Windows installer for the
[latest release](https://github.com/gotthardp/python-mercuryapi/releases) and Python 3.6.

If you get the "ImportError: DLL load failed", make sure you have the
[Microsoft Visual C++ 2010 Redistributable Package](https://www.microsoft.com/en-us/download/details.aspx?id=5555)
installed.

To build an installer for other Python releases you need to:
* Download the latest [Mercury API](https://www.jadaktech.com/products/thingmagic-rfid/thingmagic-mercury-api), e.g.
[mercuryapi-YEATS-1.31.4.35-1.zip](https://www.jadaktech.com/wp-content/uploads/2020/01/mercuryapi-YEATS-1.31.4.35-1.zip).
* Go to mercuryapi-1.31.4.35\c\src\api\ltkc_win32 and run `gencode.bat`
* Open mercuryapi-1.31.4.35\c\src\api\ltkc_win32\inc\stdint_win32.h and comment (or delete)
[mercuryapi-AHAB-1.35.2.72-1.zip](https://www.jadaktech.com/documents-downloads/thingmagic-mercury-api-firmware-v1-35-2).
* Go to mercuryapi-1.35.2.72\c\src\api\ltkc_win32 and run `gencode.bat`
* Open mercuryapi-1.35.2.72\c\src\api\ltkc_win32\inc\stdint_win32.h and comment (or delete)
the block of `typedef` for `int_fast8_t` through `uint_fast64_t` (8 lines)
* Download the [latest pthreads-win32](ftp://sourceware.org/pub/pthreads-win32/dll-latest)
* Download the [latest pthreads-win32](https://sourceforge.net/projects/pthreads4w/files/pthreads-w32-2-9-1-release.zip/download)
binaries (both .dll and .lib) for your architecture and put them into
mercuryapi-1.31.4.35\c\src\pthreads-win32\x86 or \x64
* Obtain Microsoft Visual Studio 2017, including the Python extensions
mercuryapi-1.35.2.72\c\src\pthreads-win32\x86 or \x64
* Obtain [Microsoft Visual Studio 2017](https://visualstudio.microsoft.com/downloads/), including the Python extensions, Visual Studio Desktop development with C++ and the individual component MSVC v142 - VS 2019 C++ x64/x86 build tools
* Open the Solution and review the
[setup-win.py](https://github.com/gotthardp/python-mercuryapi/blob/master/setup-win.py)
* Verify the `mercuryapi` directory
* Set `library_dirs` and `data_files` to the pthreads-win32 you downloaded
* Set `library_dirs` and `data_files` to the pthreads-win32 you downloaded and update to `x64` if required
* Set Script Arguments to `bdist_wininst -p win32` (default) or `bdist_wininst -p amd64`
* Start setup-win.py (without debugging)
* To build with python > 3.8 use `python setup-win.py build install` or `python setup-win.py build -p win-amd64 install`

If you get the "ImportError: DLL load failed", make sure you have the
[Microsoft Visual C++ 2010 Redistributable Package](https://www.microsoft.com/en-us/download/details.aspx?id=26999)
installed. Since python 3.8 adding the egg install directory with its dependencies via [add_dll_directory](https://docs.python.org/3/library/os.html#os.add_dll_directory) might be required.
