If you are planning to participate in the next Wednesday lecture on MTS, you should have MTS installed. If you are running Win9x or NT4, install the NT4 Option Pack (yes, even on Win9x). If you are running Win2K, you already have what you need. You can find the NT4 option pack on your Visual Studio disks or download it from the Windows web site. If you are running NT, make sure you reinstall any service packs after installing the Option Pack.
