I use this one:Is there a list or app to set the block app in firewall?
https://www.majorgeeks.com/mg/getmirror/folder_firewall_blocker,1.html
uninstall it and go with last working version which is 20284. All after this doesn't work well, Adobe might find a way to bypass last Medicines.Thanks, but Acrobat versions lately despite patching and blocking them through firewall and host file become unlicensed within minutes, hours or a few days then self closes
Any help would be appreciated from those that know a way around this issue
