Adobe XI pro Licencias

Did you have the software installed on decommissioned computers? You will need to deactivate first to liberate the serial number for a new installation.

You will need to contact customer care for resetting the activations.

Adobe customer care can be contacted by beginning a secure chat session at https://helpx.adobe.com/contact.html?rghtup=autoOpen. Pop-up blockers need to be disabled, you need to accept cookies! If the chat window fails to open, or is non-responsive, use a different device and/or browser to start the interaction.

Type Agent to get a human on the chat.  You will have to ask for a reset of the activation count.

Important: Adobe does NOT contact you unsolicited by e-mail or direct message. If you get contacted by direct message from a person, claiming to be an Adobe employee, look at that profile and look, if they bear the “Adobe Employee” marking under their name. Adobe support does not use Skype to give you support.
If in doubt, ask the forum.
