I have a CS 6 license I am trying to activate on a new computer but I keep getting a "Installed on too many devices" error. I have no idea what devices it's installed on and they're not mine. What do I do?

Your CS product license came with 2 activations. 

If the machine(s) on which it was activated were lost or died, sadly those activations can’t be recovered through deactivation.

Option 1: Photoshop Elements (3 year license)

Option 2: Annual Photography Plan (PS & LR bundle)

Hope that helps.

Please try to simply resset your password and you should be able to login to your new device. Cheers! 

p.s. this should be in the download & install forum.

Have you changed any major hardware (hard drive, mobo, etc.)?

That might count as another activation.

the only way to restore an activation is to use a computer that has a current activation and that meets adobe’s security requirements.

if that’s impossible, it’s impossible to restore an activation.
