Welcome to WinGAMESS.

This version is the complete, standard unix version of GAMESS precompiled on Windows using the Cygwin environment. The archive contains the required Cygwin library so there is no need to install the Cygwin environment to run these executables.

To download the binary installer just click below and enter the username of source and the password contained in the email you should have already received.
WinGAMESS.current.msi

The file is a microsoft setup and installation file (.msi). Once downloaded you just need to double click it and read the instructions. All post Windows-2000 installations should have an msiexec to run it. Otherwise you can check here for an update from microsoft.
