I am trying to run the C51 version 5 compiler on a Windows 2000 Professional machine. When c51.exe is invoked in a DOS box, the box hangs. I have made the settings, described in http://www.keil.com/download/files/nt_uvwin.pdf, but UVWINRUN.EXE hangs and C51.exe hangs. There is no difference, if the dongle is connected to LPT1 or not. Does anyone know a way round this problem to allow C51 V5.x to run on a Window 2000?
C51 V5 was released in 1994 (5 years before Windows 2000 was available). C51 V7 is the current release. It works with all current windows platforms (2K/XP/NT/98). There have been hundreds of new features added since V5--not to mention the number of new 8051 chips that have been developed since that time. Perhaps it's time to upgrade. Jon
