When attempting to use the Qi tutorial, I did raco new qi-tutorial in a subdirectory of my home folder. Unfortunately, my Windows username has a space in it. Accordingly, I get the message 'C:\Users\Byron' is not recognized as an internal or external command, operable program or batch file., probably because the path isn't quoted in whatever script is being run.
I also tried raco new rosette in a different subfolder to make sure it wasn't an issue with the qi tutorial specifically, which also failed in the same way.
Specifying the path explicitly (whether as . or the quoted full absolute path) also encounters the same error.
