Can't install cs5 upgrade to cs3 on mavericks
I have cc subscription on my mbp2.5ghi5 2011 16gb/750SSD with 420 free. I tried to put my cs5 upgrade on the machine so that I could work with a new client who needs work in cs5. I couldn't install so I put cs3 back on the machine to give the upgrade software to " find". Still can't upgrade. I am running 10.9.2. CS3 installed fine, works ok, just put it there to get the cs5 on, and I can't get the upgrade installer to work. I can't wipe the 750SSd just for the sake of putting cs5 on temporarily, I need all the cs6 and cc software to keep working. I can't use the cleaner because it will damage the software I now have on there. Any ideas?
