I just tried running ctrclient.exe using the batch file and it seems it doesn't work in my laptop. It spews out the error "ctrclient32.exe" is not a valid Win32 Application. This happens on the laptop that has Windows XP professional 32-bit. It is running fine on my Desktop which runs on Windows 7 64-bit though. So I'm curious about it. Does the ctrclient.exe require any specific kind of Windows or runtime?
