Heroku CLI Windows v7 setlocal recursion error

Issue

The Heroku CLI for Windows version 7.0.12 and earlier contains a bug that can produce a recursion error.

Resolution

The recursion error has been patched in version 7.0.13, however the bug may render earlier versions of the CLI unusable. To fix this, delete the CLI client folder at C:\Users\<username>\AppData\Local\heroku\client then run heroku update.
