Add-in installed but Audio Wizard still tries to install

I, too, am experiencing this on multiple XP machines.  Upon running the Audio Setup Wizard, the initial dialog recommends installing "the latest Add-in", whether or not the Add-in is already installed or not.  This, in itself, would not be a problem, except that the session is hanging at the smaller "Loading Adobe Connect" screen.  This smaller window must be closed with the red "X" and the larger Adobe-icon branded screen must also be closed with the red "X".  It is then possible to relaunch the session by clicking the "Open session in another window" link in the IE 8 browser window that also states, "Session will be opened in the "Adobe Connect Add-in." (Forgive descrepencies in details; I am writing this from memory.)

I contacted an Adobe rep who agreed that in Connect 6, the Wizard did not offer to install the Add-in if it determined the Add-in was already installed, but that in Connect 7, it offered to install the latest Add-in regardless of the existence of the installed Add-in.  If it didn't hang, it would be only a minor waste of time.  As it happens on classroom machines with users already only marginally comfortable with the technology, I question the logic of the blind Add-in install, and want to know when Adobe will solve the hanging of the Add-in being installed on top of the Add-in.

Anyone else experiencing this in Connect 7?

Any chance it won't occur in Connect 7.5?

Could we manually install the Connect 7.5 Add-in even if our server is still at 7.0?

Thanks, in advance, for any insights.
