Moved Photoshop CS3 to different region, new serial number not valid

[j_lopez_huesoj35975416]

Hi there!

After changing computer (Mac), my CS3 asked for activation, which I know is no longer possible. I've obtained the new SN and downloaded the installer following the steps from official sites, but I immediately find the "red mark" when I write it in the prompt at the application startup. After checking many posts and discussions, my only guess is that the installer is sent for Western Europe, which is where I am at present, while the product box was bought many years ago in the USA so maybe they are sending a USA serial number for the product installation. Does anybody know whether this could be the problem? In this case, what solution do I have? This was not a cheap buy. I hope I can still use it despite my having moved somewhere else!

Thanks beforehand

You have to uninstall the old cs3 and checkmark "remove serial number" to erase the old serial from your system.

If you have, revisit Activation or connection error when starting CS3 or Acrobat 8 and try your old serial number again.

At the bottom of this page is "Change Region". You can then set it to United States and try again.

Best practice is to copy and paste the new serial number into the new installer. It reduces the chances of the numbers transposing.

Thanks, Gene, for your prompt answer but I'm afraid it didn't work. I changed region but I got exactly the same SN. I was very careful when writing/pasting it.  No PS so far

I don't understand how the product box comes into things. There is a new installer and new serial. The product box should stay inside a cupboard, untouched and unseen...
