WIXBUG:4416 - MBA on Win7 RTM with .NET 4.5.2

(Rebased) Fail fast when loading an MBA on Win7 RTM with .NET 4.5.2 or greater installed.

Testing notes: this only occurs on x64 Win7 and only if the bundle wasn't started elevated.  Server 2008 R2 (which is only x64) works fine.  When run in compatibility mode the bundle works fine (if set to XP it gives a UAC prompt when it launches, if set to Vista it elevates normally).
