If I want to start Minecraft nothing just happens, it's like I've never clicked the icon, I've tried everything but I do not know what I'm doing wrong? I even uninstalled and reinstalled Minecraft, but that did not help either.

Do you happen to know how to fix it?

Maybe you do not have the latest Java version? You can get them here:

https://java.com/.../download/

OK, just see "everything tried" → No idea

Did you uninstall the program via windows, or did you delete the% appdata% folder .minecraft?

Often not all data of the program are deleted via Windows.

Sm

I tried both! : /

Sm

Thanks, I already have! : /

Ru

Ok, Was it a raw installation, or did you add mods and shader packs?

Otherwise try to reinstall Java completely (The Runtime Environment)

And if it still does not work, try to reset the PC to the last working time.

Do you have any new programs installed in the meantime?

Sm

Hm, I do not know, various games from my childhood, as well as SimCleaner

Ru

Especially this "tuning and optimization software" like to delete data that are actually important.

Thanks for your answers I have now uninstalled Minecraft again and deleted the Minecraft folder before that (before that I did either one or the other) and now I've lost my Worlds and Texture Packs but it does not matter

Ru

You could have saved your worlds. If you are lucky, you can restore the previous version of the folder (with the worlds), but only if you have made regular backups.

Which operating system do you have? Sometimes Windows 10 has its problems… And which launcher? The new or the old? If you mean the new then try the old times.

Has already done! ^^
