Error 6 moving Photoshop CS4 to new computer.  Old computer with Sierra operating system worked just fine.  When I just bought a new computer, I get error 6.  I need my photoshop on my new computer. I love the old photoshop.  I don't want to switch!  I am 70 years old.  It will be very hard to learn new software at my age!

Hi Judith,

You can't drag Photoshop from one computer to another as it doesn't bring over all the required files and licensing. You need to reinstall the software using the installer and your serial # to properly activate it. You can download a CS4 installer from here: https://helpx.adobe.com/creative-suite/kb/cs4-product-downloads.html

For additional information see: http://feedback.photoshop.com/photoshop_family/topics/how_do_i_download_photoshcs6_onto_my_second_computer

Please note, CS4 is very old and is not officially supported on macOS Sierra. (Printing from old versions doesn't work on Sierra)

I have used Photoshop cs4 on Sierra operating system on my Mac 2012 model.  I tried to download the software on my new MAC but the setup won't open up.  I have my serial number and just want to use the great old Photoshop cs4.  The program works fine on Sierra but I just can't transfer my photoshop or download it!  I am so frustrated.  Can I get around using setup- because it looks like Sierra doesn't like the setup program.  Thanks for all of your previous help!
