I run XAMPP on a portable hard drive, so that I have a basic server wherever I go. I got it from PortableApps and seems to run fine. It has a tutorial that I just followed and everything worked for me. I tried to install it on Windows Home Edition and it wouldn't work, tried it on Media Center, still nothing, then tried it on Pro and it works fine. Maybe it has something to do with the file systems, I have no idea. NTFS vs Fat32 ? Not sure really, but seems to run fine on my machine. Oh, and if you have installed MyApache on your machine then try to install XAMMP or visa versa the second installation wants to feed off of the other, so you need to wipe both off your system then start with one. I had that problem at first too.
