I recently purchased a third computer so I have a computer in three different locations. Is there anyway to install photoshop on all 3 computers? It tells me to "buy" a serial number, but doesn't really tell me how to do that, where to do that or how much that is. I am currently using CS4 on mac 10.8.
In the event I have to deactivate the oldest machine, how do I do that.
We do not sell CS4 products anymore since the latest version i.e. CS6 is out. You can try searching on the internet for any authorised reseller selling CS4 products(be sure to check that are not selling any pirated software).
