Yeah interesting. The paths we get are from using exec.LookPath, however those shouldn't be installed in your profile path. I will check today or tomorrow. I have a feeling this may be related to this code:

func (p *ProgramHelper) RunCommand(command string) error {
    args := strings.Split(command, " ")
    return p.RunCommandArray(args)
}

Can confirm this doesn't occur on Linux:

I'm unable to reproduce this. I tried in git bash, powershell and command prompt:

I've been able to replicate this, I get the same issues as reported when I have a space in my User Profile Directory. Spaces in sub-directories have no impact, but definitely causing problems if it's in the User Profile directory. Bit of google-fu showed me that it seems to be a problem with npx specifically: https://github.com/npm/npx/issues/14

Edited my User Profile to remove the space and fix a bunch of registry entries and now this works for me.

Thanks for reporting this info! How can we bet warn people about this? Would love to update the docs with a fix.

If it were me, I'd just add a note to the Windows Getting Started page under the npm header with a link to the npx issue for clarity, there are some workarounds in the thread and linked issues that people could try.

I opted for not wanting a space in my User Profile entirely which isn't the only way around this.

I have added the suggested note to the docs as suggested 👍
