I bought Photoshop CS3 years ago, like out of a box, not a download (probably about 6 years). It had been working like a charm, but just the other day it won't open and gives me a message that "license has stopped working for this product." Anyone have any ideas on how to get this working again?
I have this same issue and have tried everything in the article you referred to.
I have just installed CS3 onto my new Windows 10 laptop and every application I open has this licensing issue. I have tried reinstalling but no avail. The FlexNet service is running, all the folder permissions are correct, the LicenseRecovery tool did nothing. Renaming the FlexNet folder did nothing.
What can I do?
EDIT: fixed. I downloaded the installer from Download Adobe Creative Suite 3 products instead of installing from the discs I originally had. Seems to be working now.
