When the appc cli switches a CLI core via appc use it will kill the running daemon process, write the new version and then exit. If a user has Studio open when switching the CLI (i.e it's installed via Studio) then Studio will attempt to restart the daemon as soon as it stops, and because the appc use process is to kill the daemon -> write the new version, Studio swoops in and starts the daemon before the cli process can write the new version.
1. Open Studio fully
2. Ensure the daemon is running appc appcd status if not appc appcd start
3. Switch to another CLI version appc use 7.1.1-master.2
4. Check the daemon status using appc appcd status
On step 4 the paths to the daemon plugins point to initial CLI version
On step 4 the paths to the daemon plugins should point to the new CLI version passed to appc use
