My standalone executable don't run on the target computer Windows XP 32 bits

I've generated a windows standalone in a Windows Vista 32 bits machine running Matlab R2008a (32 bits).

The standalone is working in some machines (Windows 7 32bits and 64 bits), but in machines Windows XP 32 bits it does´n run. It appears for me only the console black, it allocates memory on the computer, but it doe not indicate any CPU use.

What could be the problem? I´ve already unsinstalled and installed MCR many times and it keeps happening the same problem.

Thanks
