Localhost

Hi,
I'm trying to setup and host a website and forum from my computer, And am woundering if
anyone here has done this and can help me.
I downloaded phpdev 4.2.3 from firepages (It's a web hosting package)
It comes with Apache, mysql. pearl ect. The instructions are not that clear (Or I'm looking in the wrong place)
A friend of mine just installed it and his is working, But I can't get mine to work
Anyway, it say's to move mysql to C:\, I did and I got the Localhost page to open ounce, I didn't change anything, I just closed it and tried to open it again to test it, but now I get an error message "Page connot be opened http - 500 internal server error"
I'm using windows xp

Can someone help. thanks

why don't you use appserv instead...
it's an all-in-one installer includes: mysql, php, perl, apache, etc.)
Very nice thingie..
