On how many computers can I activate my apps? You can install your apps on multiple computers but activate them on two computers at a time. See On how many computers can I install my apps?

Why do I need to activate or deactivate my apps?

Activation validates your software license by contacting Adobe servers periodically. The frequency depends on the app and your plan.

Say someone were to have hit the trial button, let the trial end, but then later on got LR 9.2 fully working with Zii ('K'ed by TNT team' in the Help menu). However, each time that person launches LR, that 'Your trial has ended' window pops up and the window layout resets upon each LR launch. I have uninstalled all Adobe software, restarted the PC, and reinstalled the Creative Cloud. Even after re-downloading Acrobat, it still says the same thing.

Deactivation disconnects your app from your computer. You can then activate the apps on another computer or later reactivate them on the same computer.

Make sure your computer is connected to the Internet.

Choose one of the following options from the Help menu depending on your app:

If you select Help > Deactivate choose one of the following options (when prompted):

If you bought a new computer and want to transfer your apps to it, simply deactivate your apps from the old computer so that you can use them on the new computer.

Uninstalled or deleted your app?

Uninstalling or deleting the app from the old computer or formatting the computer does not deactivate the app.

Old computer no longer available?

If the computer on which you installed the product is no longer available (for example you have lost the computer or formatted the hard drive or the hard drive has crashed), you can deactivate your apps from the account management page. Then install the apps on the new computer and follow the onscreen instructions.

If you have more than one Adobe ID, check that you are logged into your account with the correct ID. If you are not logged in with the correct ID, sign out and then sign in to the Creative Cloud desktop app. For more details, see Stop Creative Cloud from showing trial mode after purchase.
