    Ps CS3 to CS4

    on5lb Community Member

      Hello,

      I upgraded since several muonths from now, but:

      I installed Ps CS3 > Activated before installing Upgrade CS4.

       

      I already unactiveted CS3, but wonder if i may deleed Ps CS3 and having Ps CS4 still running correctly ?

       

      I have the same situation with Ai CS3 to CS4.

       

      I also installed Id CS4 and wonder if i can install the same product on my laptop ? (Two different computers !).

       

      Any advice please ?

       

      Thanks in advance,

      Jean

          Unless you're short on disk space, it's usually good advice not to deactivate / remove an older version of Photoshop.  Multiple versions can happily coexist, and sometimes the older versions have features that have been deprecated in the newer.

           

          Removing the old version after installing the new one has been reported to sometimes cause problems with file associations (e.g., double clicking a file might not open it in CS4 any more).  That can be overcome by reinstalling the new version or making some registry tweaks that can be found with a search on this forum.

           

          And yes, you're allowed to install Photoshop on two different computers.

            Hi Noel,

             

            Thanks for your reply,

             

            I already expected that, and left both CS3's installed (room enough).

            But i unactivated Ps CS3 (only) do i have to reactivate ? I don't think so.

             

            What about using the same Id CS4 on two different computers ? Possible ?

             

            regards,

            Jean
