I made a new partition on my new iMac so I could make a
clean install of OS 10.7 Lion. I
installed most of my important apps with no problem including Photoshop CS4 and
Photoshop worked fine at first; I was able to edit and print photos. Two days later, after installing more
apps Photoshop wouldn't launch claiming error 150:30. I contacted Adobe customer support and paid $40 for phone support
for this problem. After more than
5 hours on the phone and following all their instructions, removing and re-installing Photoshop
several times and re-installing Lion several times now it won't even let me install Photoshop CS4 claiming the installer is
corrupted. The disk works fine on
another Mac.
