 ## Known issues
 * PyESAPI is not compatible with vscode-jupyter plugin which uses multithreading. ESAPI only allows for single-thread access to objects.
 * Python 3.12 may require Microsoft Visual C++ 14.0 or greater. If you are using a VIC environment, you can get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/
