I have to update LuaTex on a win2k machine. But I get two errors while running mtxrun.exe and texlua.exe resp. via first- setup.bat. There is a call to getnameinfo in WS2_32.dll which is available in winxp and above. Here is an info from ms how to deal with this: "The getnameinfo function was added to the Ws2_32.dll on Windows XP and later. If you want to execute an application using this function on earlier versions of Windows (Windows 2000, Windows NT, and Windows Me/98/95), then you need to include the Ws2tcpip.h file and also include the Wspiapi.h file. When the Wspiapi.h include file is added, the getnameinfo function is defined to the WspiapiGetNameInfo inline function in the Wspiapi.h file. At runtime, the WspiapiGetNameInfo function is implemented in such a way that if the Ws2_32.dll or the Wship6.dll (the file containing getnameinfo in the IPv6 Technology Preview for Windows 2000) does not include getnameinfo, then a version of getnameinfo is implemented inline based on code in the Wspiapi.h header file. This inline code will be used on older Windows platforms that do not natively support the getnameinfo function." Hope this can be done. Wolfgang
