[angelica-soares]

All the time I tried to open the  APP Adobe Acrobat, this message appears: "Connect the computer to the internet to validate the serial number."

What I have to do? I tried many things that doest'n work.

Are you using a version of Acrobat older than version X?

Hi Angelica-soares

We are sorry for the trouble. As described you are getting the error 'Connect the computer to the internet to validate the serial number.'

Would you mind sharing the version of the Adobe Acrobat application you are using?

Are you using a CS6 product? If yes, you may please refer to the steps provided in the help article Error unable to validate serial number | CS6 and see if that works for you.

You may also refer to a similar discusion on an old thread Solved: Re: Unable to Validate Serial Number - Adobe Support Community - 9924116
