Problems re-installing CS5 in Yosemite 10.10.3
Following the abject failure of Migration Assistant on my new Mac to migrate my software from Mavericks on a SATA SSD on an old Mac Pro to Yosemite on my new Mac Pro (2013). I deleted the old, non-functional installations and tried to re-install from the install file I had obtained a couple of years ago (and which I had used successfully to install CS5 on Mavericks.
In the meantime I had downloaded and installed the Java for OS X 2014-001 files - and rebooted.
The CS5 installer went 99% through the install and then asked me to quit some software. I quit e.g. Firefox and Safari, but there were two other processes (Safari notification processes not Safari itself) that I could not quit from. So I stopped the install.
It told me it had installed all programs but AI. So I then tried to run PS.
This showed a dialog telling me it needed Adobe Installation Manager but that was missing or damaged and i should install a copy from the Adobe website.
So I downloaded it and tried to install but then I got the message telling me download Adobe Support Advisor. But when I went to the URL advertised for this, I find ASA has been discontinued.
So I am totally stuck.
I have tried to close the notification processes by turning off Safari notifications, but even after rebooting there is still one Safari notification process running.
How do I get the CS5 installer to work to 100% completion?
