Due to the unavailability of numpad keys on a laptop, trainers are difficult to use properly, and most people end up using keyboard re-mappers and messing up stuff. So I figured this out recently for Win7.
Click on your start menu, type in keyboard. Click on On-Screen Keyboard, the virtual keyboard now opens, then click on numlock which is on the bottom right. Then the numlock keys now appear.
Just decided to share this, because, its been hell trying to re-map keys just to use trainers.
Hope people find this useful.
