I downloaded the game(after I bought it) and both exes, and the jar don't work, sometimes I get a window named java virtual machine launcher, saying: Could not create the java virtual machine.

I run on Xp, the browser version works, my java's up to date, and last time they just told me the file for minecraft was corrupted, but I've redownloaded it more times than I can count, deleted the temp and appdata minecraft folders, and so on and so on.

could someone make a tutorial on how to fix it?
