Nothing to try yet
AppifactRepl currently only runs unsandboxed and does not work on Windows
What
The process that starts an AppifactRepl session refuses to run on Windows. It also has no way to run inside a sandbox (an isolated execution environment) yet: it only runs commands unsandboxed, and if unsandboxed commands are disallowed for the session, it refuses to start at all.
Why
Anyone on Windows, or in a session where only sandboxed commands are permitted, won't be able to use AppifactRepl for now.
