Is there a known workaround??
Not being able to install ARD from fresh via 10.7 is a real oversight by Apple and hopefully they'll bring out an updated installer soon.
You have to remember that Lion was designed as an upgrade. On my clean Lion install I've noticed a few things missing that where in my Lion upgrade install.
Such as? Were these core components?
Some of the default user pictures, all but the generic printer drivers, all but two screensavers, most of the default desktop wallpaper, some of the alert sounds. Simple silly things like that. My guess is that this stuff was removed from the Mac App Store version to make the download smaller. If its already on the users' hard drive and it hasn't changed from Snow Leopard to Lion, why replace it?
K those don't sound very core. I just finished setting up a clean Lion install and was going to bang my head against the wall if I had to reinstall SL to get back some components.
I called Apple tech support today and did get a viable workaround. It worked for me, and it'll work for others as long as they have a spare Mac OS X 10.6 station they can use for a few minutes. As far as I know, this is the only current workaround.
1. Install RDA 3.3 on a different Mac running OS X 10.6.
2. Patch RDA up to 3.5 on that Mac (you don't have to launch RDA to do this -- either use Software Update or if you have the updaters downloaded, just run them one-by-one until you've patched RDA to the current 3.5 version).
3. Copy the RDA applications from your 10.6 station to the 10.7 station.
4. Launch RDA and continue your setup normally from this point on.
5. Go back to the 10.6 station and delete the RDA app, since you don't need it there anymore.
My RDA is up-and-running now!
