Computational Chemistry Pre-Compiled Binaries for Windows

Pre-compiled binaries of computational chemistry programs can save the time and trouble of obtaining and compiling the program source code.

The binaries discussed on this page have been tested on Windows XP SP2. Installation requires administrator priveleges.


  1. Gaussian 98 is a commercial software product and must be purchased from Gaussian, Inc. A CD-ROM with the Gaussian 03 Windows binary will be mailed to the customer.
  2. Insert CD. Setup program will automatically run. If it does not, double-click "setup.exe" on the CD.
  3. Specify user information and directory locations
    Provide serial number
    Accept the destination location of C:\G03W
    Accept default suggestions
  4. Run a test job using Gaussian 03W windows interface
    From the Start Menu, start All Programs: Gaussian 03W: Gaussian03W
    Use File: Open to open c:\g03w\tests\gjf\test000.gjf
    In the Existing File Job Edit window, choose File: Exit
    In the Gaussian03 window, choose Process: Begin Processing...
    Provide an output filename, such as My Documents\test000.out
  5. Run a test job from the command line
    Open a Command Prompt window
    > cd c:\docume~1\%USERNAME%\mydocu~1
    > mkdir g03
    > cd g03
    > copy c:\g03w\tests\gjf\test000.gjf test000.inp
    > path=%path%;c:\g03w
    > set GAUSS_EXEDIR=c:\g03w
    > g03.exe test000.inp test000.out
    > more test000.out
  6. Notes:
    • The scratch directory is the current directory
MOPAC 2009

  1. Request password (free for academic use) from MOPAC 2007 website:
    A password of the form 12345678a12345678 will be sent to you in an email message
  2. Download the "MOPAC2009 for DOS under any Windows" version (Mopac2009_for_all_WINDOWS.zip) from
  3. If using Vista (or Windows 7?), open Control Panel: User Accounts, and turn User Acount Control off
  4. Create the mopac directory, which must be C:\Program Files\MOPAC
  5. Copy all the files ("Example data set.mop", "Installation instructions.txt", and "MOPAC2009.exe") from the downloaded distribution into this directory
  6. Install the password file
    Make a copy of "Example data set.mop" and rename it "12345678a12345678.mop" where 12345678a12345678 is your password.
    Open a Command Prompt window
    > cd "C:\Programs Files\MOPAC"
    > MOPAC2009.exe 12345678a12345678.mop
    which will create the file "password for MOPAC2009"
  7. If using Vista (or Windows 7?), open Control Panel: User Accounts, and restore User Acount Control to previous setting
  8. Run a test job from the command line
    Open a Command Prompt window
    > cd c:\docume~1\%USERNAME%\mydocu~1
    > mkdir mopac
    > cd mopac
    > copy "C:\Program Files\MOPAC\Example data set.mop" h2co.mop
    > "C:\Program Files\MOPAC\MOPAC2009.exe" h2co
    > more h2co.out
  9. MOPAC documentation
    The online manual for MOPAC2007 covers everything in MOPAC2009, except the MOZYME feature designed for linear scaling of larger molecules
  10. Notes:
    • mopac executable MUST be in C:\Program Files\MOPAC
    • The "MOPAC for DOS under any Windows" version is required for WebMO
NWChem 5.0

  1. Request download information from the NWChem website. A URL, username, and password will be faxed to you (typically within one week)
  2. Login to the NWChem download area and download the binary for NWChem 5.0 built for Cygwin:
  3. Create a nwchem directory, for example, C:\Program Files\nwchem
  4. Use WinZip or an equivalent package to untar and unzip the downloaded files into the nwchem directory. If using WinZip, you MUST turn of the "smart" tar cr/lf conversion option under Options:Configuration:Misc to preserve the unix format (LF line endings) of text files; otherwise, they will be converted to DOS/Windows format (CR/LF line endings)
  5. Download and copy the file cygwin1.dll into C:\Program Files\nwchem\bin\ so that it is in the same directory as nwchem.exe
  6. Run a test job from the command line
    Open a Command Prompt window
    > cd c:\docume~1\%USERNAME%\mydocu~1
    > mkdir nwchem
    > cd nwchem
    > copy c:\progra~1\nwchem\examples\h2o\h2o.nw h2o.inp
    > set NWCHEM_BASIS_LIBRARY=c:/progra~1/nwchem/usr.local.lib.nwchem/libraries/
    > c:\progra~1\nwchem\bin\nwchem.exe h2o.inp >h2o.out
    > more h2o.out
  7. Notes:
    • The scratch directory is the current directory
    • Input files must have "unix" line endings (LF), not "DOS/Windows" line endings (CR/LF)
