Adobe Application Manager stuck at "About 2 seconds remaining"

I've successfully installed Macintosh CS6, the apps launch and run, and I checked for updates.

There were a bunch of updates for CS6 so I ran the udpater.

Everything seemed to go smoothly but the Adobe Application Manager says the following (see pic below):

Update Progress

Currently Updating Adobe Extension Manager CS6 Update...

About 2 seconds remaining (100% complete)

Can I quit or force quit the application manager? It's been stuck for about 20 minutes. I've launched several apps (post update) and they seem to be working.

Thanks for your help,

Nate
