If you are having trouble with the intent launcher even after 5.3, or you just prefer to use the original launcher.

  1. Place the ZeroDay folder containing the ZeroDay.jar and .json into .minecraft/versions
  2. Create a profile in the launcher and select release ZeroDay
  3. Open the advanced settings at the bottom and press browse
  4. Find a javaw.exe in Program Files/Java/<your version>/bin/ and save the profile
  5. When you launch the client, it should not crash.

These instructions apply to Mac and Linux as well, you however need to find the respective java executable for your operating system.

Awesome, it worked!

    IntentStore Jo that dosent work at me i tried nearly all java versions the launcher and everything that got posted about but doesnt work

        CxlledNico I made a correction to the tutorial because I missed a folder, but screenshot the Java folder and post

          No need for -noverify now, then?

            it works when i launch it up but it crashes when i join hypickle

            IntentStore ^ For the reply above, we've had that happen to somebody before. How did we fix it?

              Foggy no idea but it may come down to a weird baritone error I’ve tried to fix in b20

                  IntentStore Oh yeah, it was Baritone and all we had to do is

                  tyronesaurusrex goto the intentlauncher folder (C:\Users\YOU\intentlauncher), find Baritone, and when you're in the Baritone folder make a folder called settings.txt . It doesn't have to have anything in it.

                        I can run zeroday in the normal launcher just fine but when I try to use the intent launcher it just is stuck at the "preparing" message when I try to run the game, any help?

                          Make sure you’re on launcher 5.3 and delete the intentlauncher folder

                            IntentStore I have deleted it multiple times, it will still keep getting stuck loading on selecting an account or trying to launch the game in the launcher. I tried the other solutions like downloading the intent jdk too but that only helped with the vanilla launcher and not the intent launcher. The intent launcher only stopped working when I updated from v4 to v5.3.

                                Man I can run all over! It’s like being sigma except my dev doesn’t strike down good youtubers!

                                  Zeroday xd. Again this is a guide so necroposting is fine
