Please delete the "opm.db" file found in:
<yourusername>/Library/Application Support/Adobe/OOBE
Note the built-in file search features on Mac and Windows will not find hidden files or folders. If you're not familiar with how to navigate to hidden files/folders on your computer:
Use the "Go to folder" item in the "Go" menu in the Finder and enter "~/Library/Application Support/Adobe/OOBE" (without the quotes). Delete the opm.db file.
