For whatever it's worth, I've run it fine in the past on windows 7. ________________________________ From: Richard Owczarzy <> To: Sent: Fri, December 4, 2009 12:53:42 PM Subject: RE: namd-l: NAMD on 64 bit windows 2007 I assume that you downloaded NAMD binary for Windows from the web site. Can I assume that you included path to NAMD in system variables? Can you check the path in command prompt? I did not bother to do that. The NAMD2.exe binary is a small file, so I copy it with every simulation. (1) I would copy it to some empty directory and add input files there. (2) I would start command prompt (cmd) in Windows7 and change the current directory to that directory. (3) Run “DIR” to verify that NAMD is there. (4) start simulation, e.g. NAMD2.EXE +p2 input.conf > output.dat “p2” indicates the number of processors/threads input.conf – your input file output.dat – show results of simulations This works for me in Windows XP and Windows 2000 32-bit. However, windows7 has this “UAC” stuff that prevents much software from running, so power users just run away to Linux….. Do you get any UAC prompt?

But, I could not run NAMD. It says "namd2 is not recognized as internal or external command...". I have included NAMD in the system variables too. Does anyone know the solution?. Any help will be greatly appreciated. Thank you, Priyan
