Probably he dont have the launcher in the game dir. :D

Make sure if you have the launcher: InjusticeLauncher.exe, the script check if is there.

if you have missing, open Compress.bat and change the line below to any file you want like: Injustice.exe

if not exist "%choice%\DiscContentPCG\InjusticeLauncher.exe" goto wrongDir

para quem quer comprimir os videos ta ai, aproximadamente 9.5 GB economizados.
tenham paciencia porque é demorado.

tradutor do tio Google:
