I was using 'Adrenalin 19' and i could add
any .exe of the game manually by providing a file path, but
did install v20.4.1 [ without clean install], and
all the previous profiles gone, and Add Game does not
work = after confirming selection of the right .exe file nothing.
Worked fine in v19, and only change was made on the system
is install of Adrenalin 20.4.1, nothing else.
My specs: Win10 x64, Radeon R9 270
