I have the same issue. I am trying to deactivate CS6 to install another on my Mac. I checked this site saying to contact the volume licensing admin but I cannot give details since someone just gave me the Mac with the programs installed. What to do?

Deactivate option dimmed or missing?
If the software you’re trying to deactivate is part of a suite, deactivate another app in the suite. Launch any app in the suite, and then choose Help > Deactivate.
If your company purchased the product under a volume licensing agreement, the deactivate option isn’t available. Contact your volume licensing administrator for help.
