@oculto You should copy the biohazard.exe and CMD files to the instalation path "C:\Arquivos de Programas (x86)\BIOHAZARD". You're trying to run from a desktop folder... Also, run in Windows 98/ME compatibility mode and as Administrator.

@_marcinho If you have AMD Video card or Onboard, run BIOSOFT.BAT If you have Nvidia, run BIOHARD.bat. If you're having low FPS, open any media file with Windows Media Player or Media Player Classic, pause the media file and minimize.
