I’ve been able to run the Brandmeister XTG Dialer on Windows 10 by following this procedure.
Visit the PyGTK FAQ page and fully read 21.1.
I installed the following items referred to in the FAQ:
Run a Windows command prompt as Administrator.
python -m pip install -U pip setuptools
python -m pip install -U requests
Exit the Administrator command prompt and then open a command prompt as a regular user.
Copy bmxtg-v1.2.zip into your %AppData%\Python directory and unzip.
Create a desktop shortcut to bmxtg.py. The “Target” should be “C:\Python27\pythonw.exe bmxtg.py” and the “Start in” directory should be “%AppData%\Python\bmxtg-v1.2”.
Be certain to review and follow the configuration notes in the README. Then, you’re ready to fire it up!
