Hardware Requirements for Torque X Builder

Are there any hardware requirements for Torque X Builder 2.0? Because I can't put it to work in my laptop (Asus M3N) nor in another laptop (Sony Vaio S2 XP). I could only put it to work in a desktop (AMD 64 processor, 2 GHz, 1 GB RAM). All three computer are running the same OS (Windows XP SP 2).

I think the problem with the Asus laptop is the graphics card. In the Vaio, TXB ran once but never again...
I really need to put Torque X Builder to work in one of the laptops. Can anyone help?
