zoffline Windows only standalone executable for Zwift 1.122.0 (166297).
Note: The executable is made with pyinstaller. An unfortunate side effect is that some anti-virus software may falsely flag pyinstaller executables as malware. This is a known issue and unavoidable. If you prefer, you can not use this exe and instead run zoffline directly from the source code (2nd installation method in the README).
