Deactivating not in the help menu

Problem: I can’t see the “deactivate” function in the help menu. I bought the license for the computer at my work and the license is as following:

License Owner: TECHCOLLEGE
License Type: Perpetual
License Volume: 2
Edition: Professional

ActivePresenter Version: 6.1.0 (Release 2017.04.11)

OS: Windows 10

Notes:

Hi Thomas,
I’ve just replied to your email. Please confirm via email if you really want to reset all current activations.

Best Regards,
