Updated launcher, get it here..
Portable Download:
http://kraftzone.net/downloads/MinecraftLauncher_v1.10.zip Installation: Make a folder like "McPortable" where ever you want, extract the above zip file into that folder, then run "Minecraft Launcher.exe", it will ask to download the rest of the files needed.
Note: It does not include the portable java, you can goto the 'Updates' tab and download the 32/64bit java portable version. Otherwise it just uses your OS java version to run (if you don't have, then download the portable java).
Setup installation download:
http://kraftzone.net/downloads/Setup1.10.exeInstallation: Same as above, only this provides a installer can also be uninstalled using it.
Changelog...
----v1.10---- 04/01/2014 ----
- Liteloader1.7.2 added
-- mods: OptiFine HD A7 Ultra, Worldedit CUI 1.7.2, TooManyItems
- The launcher can now read /version/ .json files, meaning you can
copy your modded library folders and minecraft versions from the
official launcher(where its easier to setup new mods anyway) into the
respective Kz launcher folders, and run them.
This will make it easier to do mod packs in the future, you can
technically make them yourself now.
-Hidden feature:
Drag and drop a .jar file onto the launcher and it will use the
launcher Java version (inc. portable) to run the jar from its location.
Useful if .jar files are set to open by something else like winrar and
not the OS system Java.
Includes some code from Atom Launcher
