Installing BASINS 4.5

The BASINS installation program copies BASINS system files, tools and documentation, and it also sets up BASINS icons automatically. Model plugins are installed separately.

The BASINS installation program allows the user to install BASINS. The BASINS system installation program installs all of these components to the local hard drive in a fixed directory structure. It also sets up a Windows BASINS program group that includes icons for the BASINS components.

When running the installation program, follow the instructions on the screen.

Tip: The BASINS installation program does not copy any BASINS data (except the optional tutorial) to your hard drive.
Tip: If you have multiple hard drives or partitioned drives, you may have only one BASINS directory in each partitioned or physical drive.
  • Note: It is recommended that the BASINS system be installed at the root of a drive. The user must have write access to the folder in which BASINS is installed. Be sure you have administrator privileges before starting the installation. Since some new system files are included in this release, you may need to restart Windows after some files have been updated before continuing with the installation.
  • If you have BASINS 4.0 or 4.1 installed already, uninstall it before installing BASINS 4.5. BASINS 4.0 project files and data will not be deleted during the uninstall process. BASINS 4.0 projects (MapWindow .mwprj files) will not open correctly in BASINS 4.5, but the map layers may be loaded into new BASINS 4.5 projects.
