Downloaded CS6 Production Premium. The dmg tries to mount even though the Download Assistant still shows activity (Extracting... this may take a while). I get the warning that ProductionPremium_CS6_LS7.dmg could not be opened. Reason: invalid checksum. This has happened 3 times in a row. Size of downloaded disk image: 5.91GB.

I did resolve the problem, but not for the reasons provided by Adobe. I reverted to the previous version 1.0.6 of Download Assistant, and the disk image immediately opened without having to download it again. So it seems that the new Download Assistant 1.2 is the culprit.
JimGoertz I would still be curious as to where you were choosing to download the install files to? Most users who are getting stuck at Extracting is due to selecting a directory/folder which the Adobe Download Assistant does not have sufficient write access too.
If you are unable to cancel the download then completing solution 1 in Troubleshoot Adobe Download Assistant - http://helpx.adobe.com/creative-suite/kb/troubleshoot-download-assista nt.html#main_Solution_1 will reset the download process.
From Adobe tech support - They had me open Terminal and type in a command to skip the verify process for the .dmg. It worked. Here's that command:
defaults write com.apple.frameworks.diskimages skip-verify -bool YES
