New Installation of Adobe DC Pro 2015 keeps requesting login information

I am having trouble with a new installation for one of our staff.  I recently installed Adobe Acrobat Pro DC, but it kept requesting a login.  I contacted Adobe, and was given instruction to use a specific download package, then during the install to skip the section where it requested a login.  I was also directed to an Adobe uninstaller utility.  I performed these steps and it was ok initially, but a week later the user contacted me that he was unable to use the product as it kept asking for a login.

So, I am looking for some suggestions to fix this issue.  I have a single user who will be stationary at his computer, so I don't desire to any login features.

Also, I would like to know if there's a way to back up custom settings.  The user has already customized the product to his liking and I am wonder if there is a folder or some specific file I can back up in the event I need to re-install.

Thanks!
