My computer doesn´t meet one of the requirements to play the game.
The CPU´s Frequency
the minimum is 1,9 Ghz. It stands that i should upgrade it. But i dont know how!
please help me

More info is needed for someone to help answer that question.
What brand is your CPU?
What model CPU?
If you know, what socket type/motherboard chip set?

Is this a custom PC or is it a "Name brand" PC?
If the later, you may be out of luck.

Right click on "My Computer", then left click on "Properties" in Windows XP and this should tell what your CPU is.

Good luck

Hey there,
I have the same problem, it was towards the end of installation that it said my CPU's freq was too low.
I just wanna know how i can upgrade it (IF it's possible)
I've put my pc's specifications below:

Processor: Intel(R) Core 2 Duo CPU T5450 1.66 GHz ~1/7 GHz
Memory: 2 GB

Thanks

Hello zuzu, just determine which motherboard exactly you have. Use SIW for that.
