If you are installing as an upgrade, the installer will check your system to find the valid upgrade product. If it cannot find it, it will ask you to input the serial number of the product being upgraded. You can also install the software in trial, then input your new and previous serial numbers in the serialization screen shown during launch.Note: In order to install additional components or reinstall your software after your original installation, you will need access to the original installer (CD, DVD or the download from the web).
Enter the serial number you received when purchasing the software in the serialization screen when launching the application. You can enter a serial number for the application itself or any Creative SuiteÂ® serial number that contains the application. If the product you purchased is one of the Creative Suites, you can enter it in any of the applications contained in the Creative Suite. Other applications installed as part of the same Creative Suite will recognize the new serial number the next time the applications are launched.
Only applications running as a trial will recognize the new serial number. If any of the applications have already been serialized with a different serial number, it will continue to use that serial number until you remove the older serial number using the Help > Deactivate > Erase my serial number. Then on the next launch of the application, it will recognize the new serial number.
Volume licensing customers cannot purchase from a trial directly, however a volume licensing serial number can be entered in the trial product. Please contact your reseller or authorized Adobe licensing center to place an order for a volume license. To find a reseller in your area, go to
If your serial number is for a different language than the installation language you select (for example, you purchased a German Creative Suite, but attempt to install it in English), you will get an invalid serial number error. Reinstall the product, choose the correct language, and enter the serial number when prompted.
The Creative Cloud Cleaner Tool is designed to run after you uninstall your Adobe application. Run the appropriate uninstaller to remove the application producing the invalid serial number error first, and then run the Creative Cloud Cleaner Tool.
However, when I try to install them, I get the following message: "The serial number you entered is not valid. Click on OK to retry entering the serial number." The serial number I am entering is correct.
I called Adobe Customer Support and they were extremely unhelpful. The only thing they said was that my serial number expired. They said they cannot help me on the phone, that I would have to get assistance through the forum online... So here I am. How is it possible that my serial number expired for the CS4 products I PURCHASED in full (not a subscription)?
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 suite's installation file (and you can choose to only install one program from the suite).
RanRan Bobandy to add to John's response I reviewed your serial number for the Education version of Creative Suite 4 Design Premium for Mac OS, and it is still valid and has activations remaining. You indicated you spoke with a member of our support team do you have a case number from your interaction that I can reference RanRan Bobandy?
If so then it is possible the licensing files were damaged when you moved to the MacBook Air. To attempt to recover, and allow the serial number to be accepted, please complete the following steps RanRan Bobandy.
That program can't find any missing stuff because I have completely uninstalled CS4 so it has nothing to link to. I have no idea what my Adobe ID was 10 years ago when I purchased CS4, I now have a new Adobe ID for CC which I am using, but I want to recover CS4 because I can't afford to pay out every month for CC. It was 10 years ago when I purchased CS4 from a retailer. Now I have no receipt, no packaging, no serial number, I have a new computer and a new email address. The only record of 10 years ago I have is the discs containing CS4 and I think I can remember my old email address.
Thanks for that link. It gave a phone number for help 800 833 6687 but when I phone it, the number is blocked. Possibly it won't accept calls from outside the USA? I'm in England. Can anyone (Adobe staff?) give me a number so I can talk to someone about recovering my serial number?
