Troubleshooting

Issue: dll not found

Solution:

xlwings32-<version>.dll and xlwings64-<version>.dll are both in the same directory as your python.exe. If not, something went wrong with your installation. Reinstall it with pip or conda, see installation.
Check your Interpreter in the add-in or config sheet. If it is empty, then you need to be able to open a windows command prompt and type python to start an interactive Python session. If you get the error 'python' is not recognized as an internal or external command, operable program or batch file., then you have two options: Either add the path of where your python.exe lives to your Windows path (see https://www.computerhope.com/issues/ch000549.htm) or set the full path to your interpreter in the add-in or your config sheet, e.g. C:\Users\MyUser\anaconda\pythonw.exe
