Question

We have two users that have been using Creative Cloud for almost a year. Recently, sometime in the last 4ish weeks, the users can no longer run Creative Cloud apps. (Yes, our subscription is paid.) Error simply says administrator access is required to install. The apps have already been installed. The users cannot run them unless they are in the local admin group.Using "Run as admin" does not work. It gives the same error.
I have opened a case with adobe support and was basically told to suck it up and put the users in the admin group. Actually, what was said was that it is "mandated that the users have administrative rights". 
There are a couple of things wrong with this. It was working for both users until recently - a recent required creative cloud update. The users have never been local admins yet the apps were working (poorly, but working).
We are in an enterprise environment and users simply do not have administrative rights on the computers.
I have changed permissions on all adobe folders, granting users or authenticated users modify or full control rights, did the same in whatever Adobe registry HKLM keys I could find. Nothing has allowed the users to run the apps - unless they are put in the local admin group.
Someone has to have a fix for this. Adobe apps have proved to have far too many vunerabilities to even entertain the idea of elevating user rights. I can't imagine that enterprise environments are allowing this.
Any help or suggestions are greatly appreciated.

Jeff,
Thank you for your response. The users in question are "standard" domain users. We do not reduce users permissions below the standard level.
The apps do not load with their current standard user permissions.
The thing that makes this odd, is that up until recently they did this issue with cloud apps. The only way I can make it work for them now is to put them in the local administrator group on their pc's - which is not going to happen.
This is what they now see. As I said before, this was not a problem up until recently they would see all their available apps. If I put them in the local admin group the apps are listed without having to install. Everything is there, just not accessible to the user.
