Hi Tariq, Thanks for your assistance. I didn't restore any backup. I installed a brand new ssd hard drive and started installing from scratch so I wouldn't inherit any errors from my previous drive, therefore this is a brand new installation of Adobe Reader which means there won't be any remnants from a previous installation. It occurred to me that perhaps it has something to do with permissions, so I will also explore that route. If it doesn't work, then I will try the cleaner tool and revert back with a response. Thank you Rute
