I uninstalled and then ran the “WinCS3Clean” application provided by Adobe here -> http://www.adobe.com/support/contact/cs3clean.html

On Amber’s computer I was unable to uninstall at first. Then I logged off her profile and then logged in under mine and proceeded to uninstall under that profile. That worked without issue.

So be sure to uninstall under the same profile you installed it under if you have multiple profiles you use.

On my laptop I ran into a problem installing CS4. It spent about 20 minutes installing and then put up an error:

“Error 1603. Fatal error during installation.” I found this page at adobe’s site -> http://kb2.adobe.com/cps/408/kb408436.html

This seems to be a common error. The fix is to go to c:\windows\system32\spool\drivers\color\ and unlock the “sRGB Color Space Profile.icm” file. Use the great freeware tool “Unlocker” to do this.

Download unlocker here -> http://ccollomb.free.fr/unlocker

Best to check this file beforehand and make sure it is unlocked, then you won’t get interrupted in the installation and have to start the install over again.
