Installed Illustrator and Photoshop from Adobe CS4 Master Collection - getting Error 5 at runtime
After installing just Illustrator, Photoshop, and any of the common components from Adobe CS4 Master Collection, and after rebooting, trying to run Photoshop it has me accept the license agreement and then asks me if I want to run the trial or put in my serial number. Regardless of which I do the app closes without any message or indication of an issue.
If instead I run Illustrator it comes up and says:
Licensing for this product has stopped working.
This product has encountered a problem which requires that you restart your computer before it can be launched.
If you continue to see this message after restarting your computer, please contact either your IT administrator or Adobe technical support for help, and mention the error code shown at the bottom of this screen.
Error: 5
I contacted chat support and they sent me here.
I've tried various things I found on the net including removing every Adobe product from the computer, deleting c:\Program Files (x86)\Adobe, c:\Program Files (x86)\Common Files\Adobe, and C:\Users\<myusername>\AppData\Local\Adobe, reboot, reinstall.
So far nothing has made a difference.
Computer is Windows 7 SP1.
Thanks in advance for any help.
