For Windows Users suing Windows 10, please use the following process when trying to install Inkcut as there is a major problem with the Twisted Package that you will face.
From the Page,
Run CMD as admin before installing any dependencies
Installation of Python and the Pyqt5 dependencies will present no problems,
When trying to install the inkcut package dependencies, you will eventually hit a wall with the Twisted package error which will indicate that Visual C++ V14.0 is needed to complete the installation.
After following the Link from the error message, and installing Visual Studio Installer from the Tools option, select the Visual Studio Build Tools 2019> C++ Build Tools and install all options
From the CMD terminal, run the following command
pip3 install Twisted[windows_platform] to ensure that the Twisted for Win32 is installed as it is always works
Then finally run the
pip3 install inkcut. It will run without any errors
Run inkcut and watch the window pop-up
Also, don't forget to add the .py scripts from the available download package to the extensions folder in Inkscape before running as usual.
