Prince of Persia The Forgotten Sands
 

please forgive me if it is not right place to post this kind of thread here.
i have dell xps L502x with windows 7 home premium X64. So, first of all i do not have numpad.
i have downloaded pop the forgotten sands it is version 1.00 and downloaded many pc trainers but my bad luck none of the trainers is working.
Please someone help me. i'll be very great full.
Regards.

I have no real numpad on my notebook either but it can emulate a numpad with the Fn button. Check out the manual.

i tried this as you told me but for me it's not working

is this because of OS different i mean Windows XP and Windows 7 X64 and all that?

No, the Fn button is processed by the keyboard, the operating system has nothing to do with it.
