Interestingly, this tool is designed to remove files related to pre-release (beta) versions of Adobe software. I haven't tested High Sierra yet, so your mileage may vary. To run CS3 now, though, I needed a new serial number I got from Adobe () using my old serial number, which no longer worked after I upgraded from OS X 10.9 Mavericks to El Capitan and then Sierra.įor the time being at least my CS3 apps run on Sierra. That said, version 3 helped resolve the installation issues I was having with reinstalling CS3 last year. This current version only works on Mac OS X 10.11 El Capitan or above. That version seems no longer to be available. I used an earlier version of this tool, version 3.10.14 to help with an installation problem with the Adobe CS3 suite.
