Mac Acrobat Pro DC invalid serial number

[gordon2008]

I just bought and downloaded the Acrobat Pro DC to update my Acrobat Pro 8 and get an error message -- This is not a valid serial number. Please re-enter your serial number. -- when I try to install. I AM typing in the correct serial number with no dashes.

Hi,

Please refer to the links below  and when you are entering the serial key , it should be  with dashes after every 4 numbers.

• Invalid serial number error
• Error "The serial number is not valid for this product" | Creative Suite

Hope this will help you.
