led. Please run the GPIB setup software from your disk. Once it is installed use ibconf to modify your settings. Under error information is says file: reginfo.c Line: 3601 and Item knownDLLs. Am I missing a file, what is reginfo.c, what is error 3601?I might recommend either copying the contents onto your harddrive and install from the fixed disk or download the NT driver from http://www.ni.com/support/gpib/versions.htm
