I have not upgraded to V8.2 yet. When I go to the download section of the Alibre site and download the software the file is not labeled to indicate that it is version 8.2.
You need to go to http://www.alibre.com, sign in, click on Account Information at the top right. Look to the left and you will see a link, Upgrade to 8.2. Click this link and then your license key will be updated to 8.2.
The 8.2 upgrade is not a forced upgrade. The email we sent to all customers should have these instructions.
