Problem installing Acrobat DC on Mac

I am on an iMac 27inch Mid 2010 running Yosemite 10.10. I have tried installing Acrobat DC a number of times, initially I was unable to do so until I removed all old copies of Acrobat using the Adobe Uninstall utilities. After that it did start to install but failed with the following message below.

What can I do to solve this problem quickly? Thanks

Exit Code: 7
