While I have replaced the hard drive I am not sure if I want to replace it prior to puting cs5 on. will I be able to add the second program on with out deactivating. Is there any thing I need to do prior to putting on?
How many times have you replaced your hard drive without deactivating CS5 on it? If it is more than 2 times now, then during activation you'll receive an error. If not, then you can install and activate without an error.
