To upgrade from 3.6.1 or 11.0:

1. Follow the instructions in the Installation & Administration manual for a single user installation, and be sure to install the software in a different location.
    
2. Launch the 11.1 Developer. When you open your profile, you will be prompted to upgrade it. The content is copied into the new content location, and the content for the previous version, while still on your computer, can no longer be accessed with the profile.

Note: Once you have upgraded, you can uninstall the previous version through Add or Remove Software in Control Panel. You must delete the old content location manually through Windows Explorer.
