Thank you. I am now using Apple Mavericks on an iMac desktop computer. My previous system was using Windows 7. Please note I have 2 sets of disks, one for each machine, but am unable to download the new Mac version of Photoshop, because I get a message saying I have to close the old download first.
I have tried removing/deleting the files on my old computer, but still get the same message saying I cannot use 2 copies of the software.
Can you help?
Regards
Oliver
