I had to upgrade my MacBook (late 2009) OS from Mountain Lion to Sierra. Once I did, my student license for Adobe CS4 Creative Suite (Design Premium) will no longer open. I get the following Error:150:30 message from the programs:
I also get this error message from Acrobat 9 (which does open for a brief moment before this pops up and then kicks me out):
I have all of the original installation CDs, but do not have my serial number and don't know how to figure out what it is because I'm pretty sure the e-mail that I used to register this in college no longer works, so I am afraid of uninstalling and re-installing. I did remove Dreamweaver from my computer to save some space, but everything was running fine without it for over a year, so I wouldn't imagine that would be the reason for this new issue. Everything was fine until the upgrade to Sierra. Is there anything I can do to fix this so the programs work again?
Thanks in advance for your help!
Getting CS4 on a Sierra system is a bit of a stretch.

Use the Search Forums Only option at the top of the forums using "CS4 Sierra" and see if there is anything hopeful that pops up beyond what is in the link I provided.
