How many copies of explorer.exe should I have on my XP system? I'm in the middle of an ongoing saga trying to install Stardock Central on my machine (see post elsewhere on this board), but I get "explorer.exe is not a Win32 app" at the end of the installation process. Out of curiosity, I searched for explorer.exe and found two copies - one in c:/windows (1008 kb, along with something else labelled as "Windows Explorer Command" called "explorer" with no extention and 1 kb in size) and one in c:/windows/system32 and 0 kb in size. Is this normal? My system is otherwise running fine, and "if it ain't broke" ... but it is just this very tiny bit broke and driving me crazy. All virus checks and spyware checks are clean. I posted a HijackThis log on my previous post, and fixed the only problem spotted there (without any effect). Thanks for any help.
