Acrobat X Pro Trial window won't accept serial number

Report · Feb 12, 2018

Had Acrobat X Pro on old computer. Have 2 license codes, original and 2012 upgrade to AcrobatSuite 1.0. During installation, Acrobat X Pro accepted one of the license codes. Now I get the Acrobat X Pro Trial popup window asking for a serial number. Neither serial number works - both generate message "This serial number is not valid for this product." Worked fine for installs on 2 other computers within the last 18 months.

assuming you're using a valid adobe serial number (6 groups of 4 numbers), you have a mismatch between your installation file and serial number. ie, you can have a valid serial number, but if it's for program A and your installation file is for program B, you will see an invalid serial number message.

common mismatches are language/region (eg, serial number is for western europe and installation file is eastern europe), platform (eg, serial number is for a mac and installation file is win), license type (eg, education vs enterprise vs individual).

and one of the most common is using a program installation file with a suite's serial number. eg, using a cs6 suite serial number with a photoshop cs6 installation file. that won't work even though photoshop is included in that suite. you must use the (correct) suite's installation file (and you can choose to only install one program from the suite).

here's official info about that error, http://helpx.adobe.com/creative-suite/kb/error-serial-number-valid-product.html
