4. Re: Install CS4 upgrade without CS3 installed?
(Emma32) Nov 6, 2008 6:45 PM (in response to 2drumstix)I have installed the cs4 upgrade but it requested for my cs3 serial #. Now I don't know if the cs3 is still useful or I can' t install it on another coputer again . Or will I still need it in the future parhaps my coputer crached and I want to reinstall all the soft ware. Will I need cs3 again before I can install cs4 upgrade.
Thanks, Emma -

P Spier Nov 7, 2008 6:42 AM (in response to 2drumstix)You may continue to use CS3, but you cannot sell or transfer it to another user without also giving them the CS4 upgrade which is tied to it. You will continue to need CS3 to re-install CS4 in the future.
