6 years ago Hi @csevast,
The kernel has never supported Tcl on Windows, because I never tested it on this platform as I don't have access to a Windows machine. If you want to make a pull request to add support I'm happy to merge it, but I don't have time or the resources to work on this anymore as I'm not often working with Tcl often.
The way it works is a bit of a trick really; Tcl gets bundled with Python as a module for some basic GUI support. Because of that we can basically pass commands to a Tcl shell through Python without any messing around with the subprocess module. I can't really remember the reason it didn't work on Windows, but looking at the code I can see I had to do something strange to get it to work on macOS. It might be a simple fix.
Thanks, Ryan

I followed the installation instructions but kernel cannot be started.
The following is the jupyter output:

I thank you on advance.
