Visual Studios C++ help

[ghost]

At work they have made some software that works gr8 but the problem is when you try to use it on a computer with more than one core it crashes :/
But when you set the core affinity to just 1 the software runs fine!

So I found this http://www.intel.com/technology/magazine/computing/Core-programming-0606.htm

But they just get confused because they have never done anything like this!?

for example

xor eax, eax
before reading eax

Could anyone shed some light on how to make software run on only one core or just to optimize more than one core?

Cheers for your time, Steve.
