# HISTORY
#
#   Version: 1.6

#   - v.1.1 Joe Farage, 08.04.2015 : support for new Adobe Acrobat DC
#   - v.1.2 Deej, 10.11.2017: fork Reader script for Adobe Acrobat DC
#   - v.1.3 amartin253, 10.15.2019: Modify Latest Version to be hardcoded until a new source path can be determined since Adobe 
#    seems to have abandoned support of the previous site.
#   - v.1.4 Martyn Watts, 24.06.2021: removed the sed -e 's/20//' as this was breaking the 2021 downloads (Lines 47 & 63)

#   - v.1.6 Martyn Watts, 28.09.2021: Added Open Console Parameter to use with TeamViewer
