I have a 2007 macbook and cs3 will not install. I didn't have any other applications open, skipped the verifying applications process and the download took over 4 hours to install, to only tell me that none of the applications were able to be installed. Will CS3 not install on this macbook. Is it too old?
Whether or not CS3 installs entirely depends on what version of OSX you use. CS3 requires the Rosetta components and those were only part of OSX until 10.6.3, optionally available until 10.6.7. if you have a newer version, CS3 won't install. The hardware is not the problem.
CS3 does not require Rosetta to run (CS2 and earlier require Rosetta). It still depends on your version of the Mac OS though. I have CS3 running on Tiger at work but you need at least version OSX10.4.11 which might be your problem as a lot of people seem to be using earlier versions of OSX10.4.
Forget about Rosetta you don't need it and it's nothing to do with the problem. CS3 should run OK on 10.6.8. Taking 4 hours to install must be a clue as that's just not right. Where did you instal from?
