product license no longer working

[riccardoc92293110]

I have a new computer. Now Adobe CS4 programs don't work anymore

I had them installed on a MAC OS X 10.6 and now I have moved them to a MAC OS X 10.11

Do you know how I can re-activate the programs? I have a regular license, the software is genuine...

When I launch Photoshop, it says this:

It says: The license for this product is no longer working

Is there a way to solve this problem?

Thanks a lot!

Hi riccardoc92293110,

Would like to inform you that CS4 is not compatible with MAC OS X 10.11.

For this you may refer to this KB article :- System requirements | Adobe Creative Suite 4, Point Products

You may try this Forum thread for PS issue :- Error 150:30. How do I fix this? PS CS4, El Capitan Mac OS X
