Convert to PDF is Not an Option in Windows Explorer

Good Afternoon,

I have installed Acrobat XI on a user's system using my account which has local admin privileges on the machine.  If I open Windows Explorer, and right click on a file, I have the options to convert to PDF or Combine Files into a PDF.  When the user of the machine logs in using their credentials, those options are no longer available and if you open Acrobat and select the Combine Files into a PDF, an error appears at the bottom stating that the files that were selected to be combined are not of the proper file type.  Meanwhile, if I try and perform this action under my account and I drag the same files into the Combine Files into PDF dialog box, it works fine.

I thought that this was initially a user access issue, but I have other users that have Acrobat installed (same version, same machine, same user access) and it works fine.  I have tried uninstalling and reinstalling to no avail.  I am looking for any assistance.  I have posted this question to Experts Exchange to no avail.  I am out of possible solutions.
