Then, I booted my Mac into Mountain Lion, launched Rosetta Stone, entered the Activation Code, and received the same exact 8111 error. After that, I was given a confirmation message that the deactivation succeeded. Then I deactivated the Rosetta Stone license under Lion and received a Deactivation Code. Once my Mac booted up, I launched Rosetta Stone, and the license verification completed normally, so I was able to use Rosetta Stone.

So today I decided to boot up my Mac with the old drive that still has Lion installed on it. I called Rosetta Stone support, and the gentlemen I spoke with thought that the problem was due to me not having deactivated the license under Lion, so the Rosetta Stone license verification server was thinking that I was trying to activate Rosetta stone on a third computer with the same Activation Code. Every other application (besides Rosetta Stone) that I had installed under Lion worked in Mountain Lion after this process was completed. Then I used the existing Time Machine backup and Time Machine restore function of Mac OS to bring personal files, applications, and settings from the backup (made in Lion) into the newly installed Mountain Lion. Then I installed Mountain Lion on the new drive.

So, I first powered down my Mac and pulled out the existing drive with Lion and working Rosetta Stone on it and replaced it with a brand new hard drive (larger capacity). 1'īefore I upgraded my Mac from Lion (where Rosetta Stone was working) to Mountain Lion, I had replaced my hard drive on the Mac. 4.1.15 under OS X Mountain Lion, I'm getting the following error during the license verification process:
