This script checks if ucrtbase.dll is installed for AoE2: DE then installs it if necessary. To run automatically before launching AoE, set your Steam launch options to

location/of/script/run.sh ; %command% %steam_location%

for example, if you cloned the repo to your $HOME directory,

~/proton_aoe2de_mpfix/run.sh ; %command% %steam_location%

if %steam_location% is not set, the script will default to /home/$USER/.local/share
