Run the file and it should detect where the game is installed, then install the patch.

• Does not work if the Community Mod Patch is installed. You can only use one.
  
• Will need a clean install of the game before you install the patch.
  
• May need a Microsoft / GFWL account that was created before GFWL was shutdown.
  
• If the game keeps stuttering / stalling, disable NVIDIA GeForce ShadowPlay.

• Can be installed on top of the Online Patch but will overwrite it and disable online play.
  
• The new characters work for all installed languages but will always use their English localisation.
  
• Known bug: Mega Man's gun and Cole's amp will appear on the opposite hand if they are Player 2.
