More and more common, the experimental snapshots allow Mojang to test the new features of Minecraft with players. This was the case for 1.18 or 1.19. However, unlike conventional test versions, they are not available in Launcher automatically. Who says Snapshot experimental, says installation… experimental?
Minecraft: Install an experimental snapshot
When leaving a new experimental snapshot, for example, Mojang publishes a blog article on the minecraft.net website. You can then retrieve, at the bottom of the post, a file “.zip”. Download it before you go to your Minecraft installation directory (accessible in Launcher settings). By default, the game is located in AppData / Roaming /.Minecraft`. Thus, it will be necessary to follow the “Windows + R” keys, enter “% appData%” and head in “.Minecraft”
Once in the game folders, click on versions. Place the.zip file downloaded previously from Minecraft (and only Minecraft.net). You can then “decompress here” with a right click. If this option does not appear, you will need to install WinRAR.
This done, you will now need to launch the Launcher and open the “ Configurations ” tab, at the top. Create a new configuration by selecting the desired experimental snapshot. Attention, if it does not appear, check the “modified” option from the previous page.
And here, the Launcher Minecraft now recognizes the new version of the game. It is now possible to select the configuration and click Play. After a little wait, the time to download the required files, the snapshot will be yours. Indeed, the downloaded.zip file does not really contain any Minecraft but only information for the launcher, indicating a file directory on the Mojang side to find.
