I am playing around with the samples in the WDK or DDK. In the HTML document, it
says "this is 64-bit compliant". Does this mean that it won't run on my
32-bit Windows XP system? I tried to install 64-bit compliant Msplotter
sample on my machine. I could not see it after a successful installation.

On the other hand, a 32-bit complaint software can run on 64-bit system. Am
I right?

I am wondering which option I should change so that I will build a 32-bit
compliant samples so that they can run on my XP.

Thanks in advance!
