Subject: [PATCH] Find Edge and Chrome where they actually install
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Test-BrowserInstalled probed App Paths under HKLM:\SOFTWARE only. Edge and
Chrome ship 32-bit installers, so on a 64-bit box their App Paths entries live
under WOW6432Node and a 64-bit PowerShell never saw them — the browser was
skipped, silently, and -Browser All configured nothing for it.

Checks the install directories first now, with App Paths (both registry views)
as a backstop, and prints which browsers it is configuring.
