I use Windows XP to run SARDU and I use no antivirus, it's basically a new PC and only has a couple things on it.
I kept copying over the missing files from XP Pro to XP Home i386 folder and around 60% it says "Cannot copy setup.exe" but setup.exe is in the root of the XPhSP3 folder and is the exact same file as in XPpSP3 so I should not need to copy it over, but it can't find that file and that's where I'm stuck now.
