Adobe creative cloud will not install on my imac27 with OS X Yosemite. The software say its not possible failure 1. Can anyone help me?

Hi,

Are you still having the issue with the install?
I would suggest to use the Adobe Clean tool to remove any partial installer and then reinstall with the updated Creative cloud

Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6

Free Creative Cloud | Download Adobe Creative Cloud free trial

Thanks

Scott
