Hey Zoe,
Did you install the apps via the Creative Cloud Packager?
If you did, you're right, changing the Default Location to /Applications didn't solve all our issues either - here's what we had to do in the end:
- Download the latest version of Creative Cloud Packager (important)
- Run the app to create your installer
- Click to change the Custom settings
- Make sure "Admin users update via Adobe Update Manager"
- Make your package and reinstall all your apps
Unfortunately you have to reinstall your apps which is painful.
It's a shame Adobe doesn't let you configure a download package taht conatins your chosen apps from the Adobe site - then you could avoid this app altogether (which seems to be aimed more at IT professionals and large site deployments).
Anyway, when we re-created the package and reinstalled, all our issues went away.
Hope that helps.
Cheers
Ben
