We've noticed this way back when Adobe Creative Cloud Packager was first launched but it's been getting annoying lately as our company has been hiring new staffs (like massively).
The repeating questions the tech support gets asked a lot is, why we haven't installed Photoshop or Illustrator or whatever software they need to use because the Creative Cloud App isn't able to detect them.
Some staff end up pressing 'install' again for every app, resulting in waste of bandwidth and time. We spend a lot of effort educating people but you can't cure stupidity.
