Serial number Invalid message

[NoisyMajor]

I have upgraded my computer and reinstalled Acrobat Pro 9 on my replacement laptop.  When I try and to input the serial number, a red cross comes up and a message saying that the serial number is invalid.   Please could you provide advice.   I have already contacted Adobe who say that “I can tell you that the license is active and working fine. Now as the license is not getting activated on your machine, that is a technical issue and i am sorry we will not be able to assist you with this product.  I am afraid, Adobe has discontinued the phone and chat support for Acrobat Pro 10 and prior version products. For the Acrobat Pro 10 and older version products you will have to go to Adobe Forums and the Adobe representatives there would assist you with the old and obsolete products.  Please go to this link and upload your issue or query and they would provide you the resolution.

Hi noisymajor ,

Please let us know the OS version on your system?

Please refer this link to check for the system OS compatibility with  Acrobat 9: Adobe Acrobat system requirements

Let us know if this helps .

I have the same situation. I "upgraded" to Mavericks (I specifically stopped at Mavericks to help CS4 to keep running until I can upgrade everything). I am doing a fresh install of CS4. First time from my discs. Had problems with InDesign, which then seemed to cause problems with Photoshop and Illustrator. Acrobat Pro 9 would not accept the serial number for the suite.

I got some help from the forums (adobe would not help in any way). And uninstalled, used CC Cleaner, etc... and then reinstalled from a DMG from adobe downloads. Everything works fine now, EXCEPT Acrobat. It still will not accept any key. I had the same problem when I upgraded to Mavericks on my main machine, and before that when I upgraded to Snow Leopard on my main machine. I got help from adobe on those occasions, but it was on the phone and happened so fast that I was unable to document it. (They did different things each time)

This has taken me all week! Reading, installing, uninstalling, cleaning, googling, chatting, trying the phone, repeat.

I actually found two keys for Acrobat 9 (not related to the CS4 key) and neither of them are accepted! (besides not accepting the CS4 key which it was installed with). Even though the CS4 key and one of the Acrobat keys are running on my main machine at home (this is for my satellite machine at another location). My main machine is turned off, so it can't be causing any conflicts.

I have posted here a lot this week! I am repeating myself over and over at this point.

Thanks Sarojini

My OS is Windows 7 Professional Edition (x64) Service Pack 1.  That shouldn't be a problem, should it?

Hi NoisyMajor

Windows 7 is compatible with Acrobat 9.

Try referring this link : Error: "The serial number is not valid for this product" | Adobe Creative Suite

Let us know if this helps.

I have a similar problem. I moved from the US to UK and to cut a very long story short, my work computer was broken in transit. I had to replace the hard drive. When I try to reinstall Acrobat 8 everything is installed, but the serial number (which I actually found on the Products  page of my account, and attached below) is apparently invalid. This is a version of Acrobat that works very well for me an does everything i need, so I'm not willing to pay a subscription to update untill i actually need some of the extras included. Help!

Regardless, Acrobat 8 can't be activated any longer, so it can't be used. Sorry, but we can't help you.

[marysjones]

Even though I have a valid serial number,  and I've used your software since 2013, eh. Oh well, I can't afford to buy into any subscription programes, so i guess it's goodbye Adobe then.

Just to clarify, this is not "my software". I don't work for Adobe, nor speak on their behalf.
