I just downloaded Acrobat 10 from the Adobe website and install went fine and perfect. but at registration screen I put in given serial number but then it said that "this serial number you entered is valid, but a qualifying product cannot be found on this computer". I was running acrobat 6.0 before this, and only 7-9 are available for selection....What do I do? Can I not buy acrobat 10 without having owned a previous version of Acrobat?
Your'e in the wrong forum. This is the Reader forum.
But to answer your question: your version is not eligible for an upgrade. You'll need to purchase the full retail version.
Which Serial Number are you using? Not the serial number per se but the type of Serial Number.
Is it a Retail,Volume or Upgrade serial number.?
