I'm trying to open the trial of CS6. I get 'invalid checksum.' What can I do?
Does the Adobe Download Assistant indicate that it is currently still downloading or extracting the software? You can override the checksum check by adjusting the preferences within the Disk Utility.
Turn off checksum? Seriously? That is horrible advice! Don't listen to him!
