- π My problem doesn't appear, I've more questions, etc.
- Problems and Questions with the SKlauncher site, such as: you can't download SKlauncher. :P
- Disable any ad blockers and refresh the page.
- Try in Incognito mode (Private / InPrivate).
- Try in another browser like Microsoft Edge, Google Chrome, etc.
- It's possible to have problems if you use Mozilla Firefox in InPrivate mode.
- Yes, just make your SKlauncher account and when it asks for a username you type the same username you had in Other Launcher.
- Obviously it must be the same: going from TheExample to theexample isn't the same thing.
- You won't lose anything because the UUID will remain the same (unless that Other Launcher has a different UUID system).
- If you used the same email you use in Discord, you can click Login with Discord.
- For now there is no "I forgot my password" option.
- Problems and Questions with the Launcher (
.exe/.jar), such as: double click and nothing happens.
- Yes, just start the Launcher with
--workDir(for example in Windows:SKlauncher.exe --workDir "C:\Games\SKlauncher")
- As the message says, you need to install Java 8 Update 60 as minimum.
- The best choice is Liberica Full JDK 8 (Package: Full JDK).
- Some Java doesn't include JavaFX (for example, AdoptOpenJDK), so you'll have to install a Java that contains it: the best choice is Liberica Full JDK 8 (Package: Full JDK).
- Assuming you have installed Liberica Full JDK 8 (Package: Full JDK) and restarted the PC: try with the
.jarfile.- Or any other Java 8 containing JavaFX like Oracle Java (for example, AdoptOpenJDK doesn't contain JavaFX).
- Try these options in order:
- Delete other launcher folders located in
.minecraft - Delete
sklauncherfolder located in.minecraft - Delete
pl.skmedix.bootstrap.Bootstrapfolder located in%APPDATA% - Check that Java is allowed in your Firewall and Antivirus.
- Install Liberica Full JDK 8 (Package: Full JDK) and restart the PC.
- Delete other launcher folders located in
- If you want to use your SKlauncher account: enable the Offline option and then type your username.
- If you want to use your Minecraft account: currently only Mojang accounts are supported, Microsoft accounts aren't.
- If there are no problems with the server (like the overload that occurred in August 2021) or problems with your connection:
- When you upload your skin/cape for the first time you should see the change instantly (if you already have the Launcher/Game open, you should close it).
- But when you want to change your skin/cape for the second, third, etc. time it may take a couple of hours to change (and it's even possible that the Launcher shows your old skin but inside the Game you already see the new one).
- So if you saved the skin/cape properly (because you go back to the website and it shows you the new one), you don't have much else to do but wait.
- Maybe the filenames are not the same as the ID, for example with the 1.18 Experimental Snapshot 7: its ID is
1.18_experimental-snapshot-7but the files and folders are1_18_experimental-snapshot-7(1.18 != 1_18)- And of course, the solution in this case was renaming the
.jsonand the folder to:1.18_experimental-snapshot-7
- And of course, the solution in this case was renaming the
- The other option may be that you incorrectly installed it. Using the same example as above, the folder structure should be:
.minecraft\versions\1.18_experimental-snapshot-7inside this folder should be the1.18_experimental-snapshot-7.jsonand other files.
- You can add
-Xmx<size>[g|G|m|M|k|K]to the JVM Arguments, for example:-Xmx2048m(2.0 GB)- Don't forget that there is a space between each argument:
-arg1 -arg2 -Xmx2048m -arg3 -arg4. And yes, these are the same (they represent 2.0 GB):-Xmx2g -Xmx2G -Xmx2048m -Xmx2048M -Xmx2097152k -Xmx2097152K
- Don't forget that there is a space between each argument:
- But if Max RAM Usage has a value assigned to it (without being visible to you), it will use this value and not the JVM Arguments you set.
- So it might be a good idea to report the problem in the Discord server.
- You must have x64 (64-bits) Java installed.
- Log in (email and password) is for Mojang (Premium) accounts, check the Offline option (read the I can't log in point) or buy Minecraft: Java Edition.
- Yes, just start the Launcher with
--demo(for example in Windows:SKlauncher.exe --demo)- If you've skin/cape, it should still be visible.
- Yes, any mod that works with Minecraft Launcher should work with SKlauncher.
- Some cases require you to enable the Compatibility Mode option.
- Hey, ask questions about SKlauncher. But in short: you need to start the game with the version you want to use mods (for example: Release 1.7.10), then close everything to install a Mod Loader (for example: Forge), start the game again BUT using the Mod Loader profile and finally you will be able to install the mods.
- As it says above: it's the same as in Minecraft Launcher, the only difference is that now you're using a Launcher called SKlauncher.
- Like Where is Minecraft installed? says, these are the 2 folders that you will found. So you just have to delete them (as well as the
.exe/.jaryou use to run SKlauncher).- If you want to be more precise and not delete the whole
.minecraft, you should delete these things:runtime,sklauncherandsklauncher-fx.jar(you might like to read this in case there are different files).
- If you want to be more precise and not delete the whole
- Problems and Questions with the game (everything that happens after pressing PLAY), such as: the game crashes with an error code.
- The Minecraft engine (LWJGL) has dropped Linux x86 support in LWJGL 3.
- Play older versions or install Linux x64 (64-bits).
- Uninstall Java and restart the PC.
- Install Java SE Runtime Environment 8u251 (
jre-8u251-xxx) and restart the PC.- If it doesn't work, jre-8u31-xxx should be installed. The Launcher starts with 8u251 but you edit the profile so the game starts with 8u31.
- The server you're trying to connect to is for Premium users (
online-mode=true).- If it's your server, then set
online-mode=falsein yourserver.propertiesfile.
- If it's your server, then set
- Well, you can always join the Discord server and use the appropriate channels.
- We only ask you to do 3 things: explain well what happens, send the logs and patiently waits for help.
- Windows:
%APPDATA%\.minecraft - Linux:
~/.minecraft - macOS:
~/Library/Application Support/minecraft- It's possible to find
pl.skmedix.bootstrap.Bootstrapin the previous folder, but it's useless for you. :P
- It's possible to find
- Launcher:
.minecraft\sklauncher\sklauncher.log - Game:
.minecraft\crash-reports\crash-YYYY-MM-DD_HH.MM.SS-client.txtand.minecraft\logs\latest.log- You can copy the logs content and paste it in mclo.gs / Pastebin (or upload the files directly to Discord). This way you send a link instead of a huge message.
