Is this the first time you have tried the launcher? You need to post the error code or a screenshot of it, I have no way of troublehooting without it.

And the launcher should work on winXP, I believe some have had it working on that OS, you need to have the .net framework (version4 is the last working version for winxp and I use that to compile the launcher with) download is here: http://www.microsoft.com/en-gb/download/details.aspx?id=17718 )

I f it work I will tell you.

ok i got it to work but only when i access it from my flash drive, why? i can open the launcher up on when it's on the computer but minecraft doesn't open. on my flash drive it lets me play minecraft, so thank you but i already know that everytime I want to play mc I have to plug my flash drive in (going to get annoying).

did you download portable java? 

goto settings and tick Debug on at the bottom, press launch, ctrl+c copy that popup dialog, minecrat not starting up probably has something to do with it being unable to find java on the pc, while on the flash drive maybe you have a portable java so it can find it.

um well it when I look in task manager it shows it starting but then seconds later it turns back off.

means java had some issue with loading the the startup file..  in the minecraft folder look for the 'logs' folder... delete any files in there.. then try launching it again.. if any new files are generated then have a look at them, they will usually tell you what is wrong when it crashes.. post them here

Ok i did the debug thing and this is what i got

hmm try renaming "New Folder"  to something else without a SPACE in it.. and see if that launches..

i got it to work but after that I found an internet signal and now I have internet but i will still use the launcher. but is this launcher 100% clear of hacking accounts and keeps passwords completely safe?

These are the only connections it makes:

Using premium Login?: Connects to Mojang login server using ssl

Downloading "Minecraft Release"  versions?: Connects to Mojang servers

Downloading launcher updates, JavaPortable, and 1.7.2liteloader(my custom modpack): Connects to Kraftzone.net

It doesn't do any automatic net connections, any connection made will always proceed a button or dialog prompt asking you beforehand.

"keeps passwords completely safe?"

Nope, if you store your premium login&password with my launcher, it saves that info locally to the file "Minecraft Launcher.xml"  that will store plain open text password. I could encrypt it, but anyone who runs the app will be able to get the password anyway because there is a Show/Hide password button.. This minecraft launcher is for really my own convenience and portability, if you are worried someone might use your computer and steal the password(s) then don't save login/password, you can just enter it everytime you 'Launch'

I can encrypt the local username/password, but just like mojangs old launcher anyone could still get the real username/password. Its pretty much why they remade there minecraft launcher, and force people to relogin to there minecraft account.

btw new launcher update to try, its still beta as explained in the post: http://kraftzone.net/forum/index.php?topic=1234.msg11988#msg11988
