How-To Manually patch a pre-release minecraft.jar
Below is how to get to the minecraft.jar file on your Windows computer so you can load a new one (ie from pre-release).
If you have the new Minecraft.exe:
- Open Minecraft (do NOT Login!)
- Click on Options
- Click on the link listed next to “Game location on disk:”
- Close Minecraft
- Open the “bin” folder
- I would then suggest renaming the current minecraft.jar file to something else (ie minecraft.jar.1_8 or so) before replacing it
- Copy your new minecraft.jar into this folder
- Launch Minecraft again and enjoy playing!
