CS6 Master Collection key no longer recognised

[Calm_Mind123]

Not sure if this is the right place for this issue, but here goes... out of the blue, my product key for the CS6 Master Collection is no longer being recognised and I have been reverted to a 30-day free trial version. Could someone please have a look into this and help me with the issue?

Hi,

Please refer to the below links:

Invalid serial number error

Warning: "Adobe Genuine Software Validation Failure..." | Windows

Error "The serial number is not valid for this product" | Creative Suite

Let us know if this helps.

Hi Barry,

You can try uninstalling and reinstalling the Creative Suite 6, also if you have any creative cloud apps installed remove them as well:

To uninstall see, Uninstall Creative Suite | CS5, CS5.5, CS6

Also see, Learn to activate or deactivate Adobe apps.

Download it from here : Download Creative Suite 6 applications
