illustrator install fail due to older version uninstall not working
Hi there,
I have downloaded the new version of illustrator but when i double click on the installer (on Mac laptop), it doesn't open/run properly. I tried deinstalling the older version (2014) that carried across when i loaded my old backup onto my new laptop. But i get error messages saying the following:

I also deleted the Adobe files from my applications folder to trash, then emptied trash. I didn't realise that this would stop me from being able to deinstall the old apps?
I would be most grateful for any tips.
Thankyou!
