I just uninstalled Photoshop CC, Indesign CC, and Illustrator CC and did not experience any hiccups.
Now time for rant:
- It's a year+ since the switch to CC; what is the utility in switching your brand's identity to a "SaaS company" if you aren't going to be doing rolling releases? You just didn't want to to package and ship the physical boxes anymore? This is mind-blowing to me. Tell your devs/architects to install some Linux instances (Arch preferably) and see they way they handle package upgrades. If you guys weren't so Linux phobic you might have picked up on how to elegantly do package/app updates.
- Who in Marketing thought "Well ****, if we are going to have a fragmented CC ecosystem might as well just stick the year at the end". If this is going to be your naming convention you should push an update to rename the old CC's (2013).
- Please refresh your Creative Cloud app immediately. As @unconsenting posted before, HD space is luxury and can't be wasted. Why not have a prompt asking if the user wants to uninstall any previous version? Before finding the uninstall file, I glanced through the CC app for a non-existent uninstall button. Ridiculous that I had to open the Applications folder(or sorting through the numerous Adobe uninstall apps that spotlight displays) and run 3 uninstall apps, each a 5 min uninstall, after spending 15 mins running the new update
