There are two ways to install Inkporter CLI on Windows. You can use the Installer or install it manually.
This is the easiest way to install Inkporter on Windows. Just make sure you put your Inkscape in Program Files. Otherwise you will have to configure your Environment Variable (I'll explain how to do this in manual installation).
Manual installation means you only download the batch script and configure everything by yourself. The advantages of using this method are that you can use different versions of the dependencies as if you're using a portable version of Inkscape. A new version of the dependencies has been released. Or you can install the CLI version.
Put it anywhere you want, but a good place to put it is in the Inkscape directory.
Control Panel -> System and Security -> System -> Advanced system settings -> Environment Variables...
Double click on the "Path" variable, then add your directory to
inkporter.bat and the dependencies directory
Try to run Inkporter from cmd
The advantage of using a manual installation is that you can use different builds of Inkscape or use it when you have not put your Inkscape in Program Files.
