Fixed: Error 150:30 (Adobe CS4 licensing problem) – MAC

by Linus Neumann on Dezember 26, 2009

The following script will solve the often and randomly occuring problem with Adobe CS4 Mac „licensing for this product has stopped working… Error:150:30

If this solves your problem (it will!) consider leaving a nice comment.
Maybe you even want to

Copy and paste this to, enter your user password when prompted and follow the instructions on the screen. During this process, as ~40MB Liscense recovery file provided by Adobe will be downloaded, executed and deleted afterwards. Make sure to view and agree with the license agreement for this piece of code before you run the script (chances are it will fail otherwise).

if [ "$(grep -o /etc/hosts)" = "" ];
then echo "/etc/hosts is already modified"
echo "" >> /etc/hosts
echo "/etc/hosts was successfully modified"
sudo rm -rf "/Library/Application Support/adobe/adobe PCD/cache/cache.db"
sudo rm -rf "/Library/Preferences/FLEXnet Publisher"
say "Now, please wait for the download to finish."
curl -o LicenseRecovery111.dmg
sudo hdiutil attach LicenseRecovery111.dmg
sudo python '/Volumes/LicenseRecovery 11.6.1/LicenseRecovery/'
sudo rm -rf ~/AdobeLicensingFilesBackup
sudo hdiutil detach "/Volumes/LicenseRecovery 11.6.1"
sudo rm LicenseRecovery111.dmg
say "Done! now start CS4 and enter your serial"
exit 0

This will perfom the steps suggested by Erik’s Brain and Jake’s Computer Blog. After completing these steps, you will need to re-enter your serial number, and CS4 will work again.

Be aware that this is not a crack! You will need a valid serial number.

If this doesn’t work for you:

  • let me know
  • check if Adobe’s Liscense Recovery tool was updated to a version other than 11.6.1 and  if so, modify this script accordingly, then let me know
  • check if you are using a Mac and if not, follow the advice given here.
  • remember that this is not a crack, you will need a valid serial number


This worked as described. Very helpful. Thanks!

The Adobe support/forum instructions for fixing the CS4 license error on 10.9.4 Mavericks did not work, but this did! I’m so glad I found it … thank you SO much! (And thank you for typing out exactly what to paste into Terminal!)

Your expertise much appreciated

by Andrew on 8. November 2014 at 19:43. #

Wow. I have been struggling with this for SO long after restoring my mac from a time machine backup (my hard drive crashed and had to be replaced).

Excellent post, it works beautifully. Thank you Thank you Thank you.

by Bryan on 10. Dezember 2014 at 21:27. #

Still didn’t work 🙁
I get the message: The serial number you entered is not valid. Click OK to retry entering the serial number.
What i did: i copied the serial number from the official mail from Adobe! Getting hopeless here…

by Stefanie on 14. Dezember 2014 at 21:59. #

Worked like magic! None of the many other so-called „solutions“ available through web searches had done it for me. Many thanks.

by billinrio on 30. Dezember 2014 at 16:47. #

Thank you very much for your work. I add my accolades to the above—worked perfectly!!!

Does this work for CS3 on Mac OS X 10.6.8


by Randy Dalby on 10. Januar 2015 at 19:34. #

Saved me hours! Thank You!

by Wolfgang Reiserer on 16. Februar 2015 at 16:04. #

WoW !! It’s just fixed for me too. i follow the steps carefully and it worked for me. Actually this is for my office mac we have all the version of adobe application so after we run this above method we had to enter the serial number again for the Adobe CS4, Adobe CS5, Adobe CS5.5 and Adobe CS6. All again i entered.
So my suggession is if any want to apple the above solution. please keep all the orignal serial number with you and then run the tool.
All the best !!
Once again thanks guys…

excellent, I think I am becoming an it wizard

by thelma on 12. Mai 2015 at 21:32. #

This fixed my problem. Thank you so much! I spent WEEKS searching for the solution to this…weeks!!! 5 minutes on your site gave me a working form of my favorite version of photoshop that I wouldn’t trade for anything. I was so upset when I found that it wouldn’t work on my new macbook which had Mavericks installed. I even made a trip to the Mac store and asked them to help me, only to be given the answer that it couldn’t be installed be it was incompatible. Never say never and never give up! PSE 6 on Mavericks lives afterall.

Thank you very much! Worked perfectly!

by Peter Felperin on 23. August 2015 at 16:40. #

Thanks so Much! After updating my OS and some apps CS4 stopped working. Spent days trying to reboot and tried every other solution for this under the sun, nothing worked.
This just made my day!
Thanks Again!

Thanks! It worked very well. 🙂

by Annika on 1. November 2015 at 00:03. #

Wow…. nothing else worked. Thank you.

You made my day! Fantastic! Thx from Germany.

by Susann on 9. April 2016 at 14:57. #

Thank you so much. I can use my CS4 again!!!

by Malik on 6. Mai 2016 at 00:48. #

I tried the official adobe tutorial and had no luck. This worked perfectly. Thank you

by Justin on 17. Juni 2016 at 08:25. #

This worked! Nothing else worked at all and I tried at least 6 different ways with Terminal from different sites, including Adobe. Now if I could only find my serial number, it’s been too many years.

by spookie on 31. August 2016 at 21:58. #

I’ve tried everything else and nothing worked. But this works! What a life, or JOB, saver!

Thank you!
