  • Problems and Questions with the SKlauncher site, such as: you can't download SKlauncher. :P

I can't download SKlauncher: Loading... / Nothing appears

  • 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.

Can I migrate my Other Launcher account to SKlauncher?

  • 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).

I forgot my password

  • 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.

🎲 Launcher related

  • Problems and Questions with the Launcher (.exe / .jar), such as: double click and nothing happens.

Can I install SKlauncher in another folder?

This application requires a Java Runtime Environment

  • As the message says, you need to install Java 8 Update 60 as minimum.
  • ⚠️ If you already have Java installed, you must uninstall it and then restart the PC in order to install the correct one.
    • Unless you know how to use CMD commands and do something like this: "C:\Programs\Java 8\bin\java.exe" -jar "C:\Games\Minecraft\SKlauncher.jar"

In your Java build - JavaFX library is missing

  • 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).
  • ⚠️ If you already have Java installed, you must uninstall it and then restart the PC in order to install the correct one.
    • Unless you know how to use CMD commands and do something like this: "C:\Programs\Java 8\bin\java.exe" -jar "C:\Games\Minecraft\SKlauncher.jar"

I double click the launcher file and nothing happens

Launcher starts but closes or keeps loading forever

  • Try these options in order:
    • Delete other launcher folders located in .minecraft
    • Delete sklauncher folder located in .minecraft
    • Delete pl.skmedix.bootstrap.Bootstrap folder 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.

I can't log 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.

Why my skin/cape hasn't changed?

  • 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.

I installed an experimental version but it doesn't show up

  • 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-7 but the files and folders are 1_18_experimental-snapshot-7 (1.18 != 1_18)
    • And of course, the solution in this case was renaming the .json and the folder to: 1.18_experimental-snapshot-7
  • 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-7 inside this folder should be the 1.18_experimental-snapshot-7.json and other files.

The Max RAM Usage is empty and there is nothing to choose from

  • 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
  • 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.

I can't allocate more than 1 GB

  • You must have x64 (64-bits) Java installed.

I can only play the Demo mode

Can I play the Demo mode using my Premium or my SKlauncher account?

  • Yes, just start the Launcher with --demo (for example in Windows: SKlauncher.exe --demo)
    • If you've skin/cape, it should still be visible.

Can I use mods in SKlauncher?

  • Yes, any mod that works with Minecraft Launcher should work with SKlauncher.
    • Some cases require you to enable the Compatibility Mode option.

How do I install mods?

  • 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.

How does Game Directory work?

  • Imagine it as the --workDir but only affecting the profile you're editing.
    • Without modifying the Game Directory (points to .minecraft): All your worlds, options, mods, etc. are in the same place.
    • Modifying the Game Directory (points to the path you set - reference image): Most files are still downloaded to your .minecraft, you will even have to install the Mod Loader (Forge / Fabric / Others) there. But the invididual mods (OptiFine / Sodium / Others), your options, your worlds, etc. will be separate.
  • If this "little explanation" and the reference image don't help you understand it, maybe you should try it yourself.
    • Something simple, like switching from a new to an old version having changed all the new controls / options. In the old one you may see your options unchanged, but when you go back to the new one they're reset. This wouldn't happen if you've the Game Directory modified.

How to uninstall 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 / .jar you use to run SKlauncher).
    • If you want to be more precise and not delete the whole .minecraft, you should delete these things: runtime, sklauncher and sklauncher-fx.jar (you might like to read this in case there are different files).

⛏️ Minecraft related

  • Problems and Questions with the game (everything that happens after pressing PLAY), such as: the game crashes with an error code.

Release 1.13 and above doesn't launch on Linux x86 (32-bits)

  • The Minecraft engine (LWJGL) has dropped Linux x86 support in LWJGL 3.
    • Play older versions or install Linux x64 (64-bits).

EXCEPTION_ACCESS_VIOLATION (0xc0000005) | Problematic frame: ig7icd64.dll

  1. Uninstall Java and restart the PC.
  2. 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.

Failed to login: Invalid session

  • The server you're trying to connect to is for Premium users (online-mode=true).
    • If it's your server, then set online-mode=false in your server.properties file.

😭 My problem doesn't appear, I've more questions, etc.

  • 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.

Where is Minecraft installed?

  • Windows: %APPDATA%\.minecraft
  • Linux: ~/.minecraft
  • macOS: ~/Library/Application Support/minecraft
    • It's possible to find pl.skmedix.bootstrap.Bootstrap in the previous folder, but it's useless for you. :P

Where are the logs located?

  • Launcher: .minecraft\sklauncher\sklauncher.log
  • Game: .minecraft\crash-reports\crash-YYYY-MM-DD_HH.MM.SS-client.txt and .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.
