Windows NT will require that you have available the original Windows NT CD or diskettes so that additional support drivers can be loaded. Specify the drive and directory location of the Windows NT files (e.g. a:\i386, f:\i386, etc.) and click on the Continue button. The files for the DLC protocol will then be installed.
As you can see below, the 32-bit DLC driver is now present in the Protocol window. You should verify that this is the DLC stack being used if a customer indicates that they have loaded the DLC drivers and they are still having problems.
