There's one; otherwise you wouldn't be able to set your Google account via the Control Panel or the Contacts portion.

You can't see it listed in installed programs, unless you enter red pill mode. I just went and installed the RTComm Beta 2.3 version without even looking at the version installed.

It very well could be the same version that came with the pre-Diablo version. I'm just curious if that's the case. Once I've installed RT Comm Beta, there are no updates, so I could think that the Beta is the "newest" version.
