Hoping to Upgrade Reader X to XI .... BUT ... (1) Control Panel shows an Adobe Reader 10.1.3 MUI at 542 MB ( 6/13/12) -AND- Adobe Reader 10.1.6 at 118 MB (2/25/13). WHAT did I do wrong to get TWO Installations? DELETE 10.1.3 - OR - Leave alone?
(2) WILL Reader Upgrade to XI have ANYTHING to do with Firefox 19.0.2 showing that the ACROBAT Plugin is OUT-of-DATE? Acrobat Plugin 10.1.6.1 shows in Firefox NOW.
(3) Have NOT seen the words "You Install Reader XI OVER X - OR - DELETE X and Install XI. Where are the HOW to Upgrade Instructions?
Thanks for any Help given.
