Installation files

In order to install Gekko as a standalone package for economic analysis, go to www.t-t.dk/gekko, and choose 'Download' to choose between a stable version or a development version (direct link: stable versions or development versions). If you have problems installing, please consult the trouble shooting guide. After installation and starting up Gekko, it might be convenient to create a .bat file to start up the program in the future (see more in the 'Setup and environment' section below).

Uninstallation

Uninstalling Gekko as standalone package can be done from the Windows Control Panel. Close Gekko, start the Control Panel and choose Add/remove programs, then select Gekko and uninstall it.

Setup and environment

Gekko uses the concept of a working folder from which files are read and written. This may be chosen in two ways:

•If Gekko is started up from the Windows start menu, Gekko will open up the last-opened working folder. You may change this by means of File --> Set Working Folder... in the Gekko main window menu (you may also choose from recent folders).

•If Gekko is started up from for instance the Windows Command Prompt (calling Windows cmd.exe, followed by typing gekko), Gekko will use that particular folder as its starting folder. This only works if a gekko.bat file is available, see Utilities --> Make .bat file for easy Gekko startup.... (This gekko.bat file should be put somewhere in your Windows path -- Gekko will try to put it into your Windows folder).

If a file with the name gekko.ini is present in the program folder (where Gekko.exe is located) or in the working folder, this file will be executed at Gekko startup. Typically such a file contains OPTION, TIME, MODEL and READ statements setting up the environment for different kinds of analyses. The gekko.ini file will be rerun when issuing a RESTART statement (or an INI statement to just run gekko.ini), so this statement is in effect equivalent to closing and reopening Gekko (in contrast, the RESET statement omits loading the gekko.ini file).

For more advanced users, there is the possibility to indicate parameters when calling the Gekko.exe file at Gekko startup. See the RUN help file for more on this.
