Hello folks
After a few days of struggling to install the battle.net app and looking over all the old tips and blizz advice from old threads, I finally managed it!
Here is what I did
updated drivers
added the battle.net app to my permitted apps list on avg
installed windows update
Deleted all bliz and battlenet files n folders:
Press Windows Key + R and type:
• %LOCALAPPDATA%
• %APPDATA%
• %TEMP%
• %PROGRAMDATA%
also go into your :c/programs and make sure the battle.net folder in there is deleted too
once youv purged all your junk files n folders
click on search an type in CMD
run it as admin
enter the following commands one at a time:
net stop winmgmt
type Y when asked are you sure
next type
winmgmt/resetrepository
then type
net start winmgmt
now type exit
reset pc and hopefully it will work for you like it did for me!
