How do you install Acrobat 11for only one user vs. all users?

Installed Acrobat 11, with updates 14 and 15 and we don't have an issue using the Add-In for Office 2007 Excel and Word.  Once we apply 11.0.16 or 11.0.17, the AddIn is no longer available.  We receive the follow message when we attempt to put the checkmark next to Acrobat PDFMaker Office COM Addin in the COM Add-Ins section, "This add-in is installed for all users on this computer and can only be connect or disconnected by an administrator".  Or was something changed in the latest updates to cause this issue?   Thank you.
