I know its no longer supported BUT, i am a retired 74 year old and was very happy using CS4 for my charity leaflets etc. I used Acrobat 9 Pro. I allowed an update to latest Acrobat, which is very nice but i cannot afford to use a monthly license - i only use it 2 or 3 times a month. I need to get Ver 9 back on but whenever i try to reinstall it stops and “preparing to install”. It installed when i first upgraded my machine onto Windows 11. Please help - i feel a little cheated because it was wall working fine. CS4 still works fine, its just the Acrobat 9 Pro that has gone.

I’m sorry but CS4 and Acrobat 9 are officially dead. The aged out activation servers no longer exist.

Hi geoff.newman@mac.com,

Thank you for reaching out, and sorry for the trouble caused.

As you mentioned, Acrobat 9 is an outdated and unsupported version, and it may not be fully compatible with the latest operating systems. If it was working well before and you have the installer available, please try reinstalling the application using the steps below:

Remove the currently installed application, then run the cleaner tool (https://adobe.ly/43Q3Kuu).
Reboot the machine
Install Adobe Acrobat 9 from the installer you have available.

Please note that there are no new updates for Acrobat 9. If you continue to experience the same issue, there may not be much we can do from our end.

Let us know if there's anything else we can assist you with.

Thanks,

Meenakshi

Hello Meenakshi, and thank you for responding. I have tried what you suggest and the installer starts working then stops at the “Preparing to Install” screen where it locks up. I did try to download the Ver 9 but it asked for my serial number. When i put the serial number of the CS4 into the programme it said it was not a Ver9 number. It is of course a CS4 number. Is there perhaps some way we could tell the Ver9 download what the proper serial number should be. I have the serial number for the CS4 - i have the discs in the box.
