I'm moving to a new computer and need to deactivate all plugins on this current computer and on an old computer that i had.
How do i do that?

Run ASC
At the top right corner, there's a drop-down near "Welcome your_username". Click on it.
Choose "Preferences"
Then choose the "Licenses" tab
There's a "Deactivate All" button there. Click it
