CS5 suite not updating on OSX El Capitan and "quit unexpectedly" warning shows on closing programs.
I have just purchased a new iMac running OSX El Capitan 10.11.1 and have installed Masters Collection CS5. I am immediately having two problems with it.
Firstly the entire suite seems to be refusing to update. Available updates are recognised by the updater and downloaded. But at the end of the process an update installation failure notice appears. This seems to include all updates downloaded.
I am not running any third party anti-virus software. I have also tried turning off the firewall to no effect.

Also when I quit most programs in the suite a notice appears saying the program quit unexpectedly. It was not unexpected on my part as I just asked it to quit. This is very annoying.

Are these problems happening to others? Is Adobe aware of these problem? Is there a solution, or does Adobe need to correct the problem? And if I can't update, how can the problem be fixed?
I trust Adobe intends to give ongoing support to its legacy products. Especially as it's new business model means I can no longer purchase updated versions of this expensive product.
