  • 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 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.
