WindFarm Release Download


This is a pre-release for release 5. Do not download or install this update unless you are a new user or have upgraded to Release 5.

If Upgrading from Release

A number of file changes have been made in this new release. Consequently the files are not always backward compatible, and therefore it is necessary to back up the data of any projects previously developed. It is also essential that all users that share files within a company are updated to the new release at the same time.

The simplest form of backup is to copy the entire default project folder C:\WindFarmR4 to a new folder, say C:\WindFarmR4Backup. You may of course be using a different drive and / or name for the default folder.

After backing up your projects uninstall your present release using the Control Panel / Add or Remove Programs. Then install the new release and your projects should be ready for use.


On Windows Vista, 7, 8 and 10 after installation please set the program to run in Windows XP SP2 compatibility mode.


The WindFarm download has been divided into 4 parts.

  • The minimum download is the WindFarm program, which must be installed first.
  • The tutorials are an essential tool for learning to use WindFarm.
  • The WindFarm 3D data is needed if you want to explore the WindFarm 3D module’s capabilities.
  • The HASP device driver as detailed at the end of this page

The WindFarm 3D data download only contains one file C:\WindFarmR4\Turh\Terrain\TTurh001.tdba that is used in the tutorials and the Quick Tour and has not changed. If you have an existing installation you could copy this file to another location and then restore it after installing the program and tutorials, thereby avoiding the large download. Alternatively it should be in the back up.

The help system and the tutorials have been updated. Also the documentation provided on the Release 5 page is similar to the tutorials and will help you to understand the new features.

WindFarm Program (105MB)


WindFarm Tutorials (85MB)


WindFarm 3D Data (205MB)



After backing up your projects uninstall your present WindFarm release using the Control Panel / Add or Remove Programs and remove your HASP, as it should not be attached during the installation procedure.

Once the program file is downloaded double-click on the downloaded file to start the installation, then follow the instructions. If the tutorials and 3D data are being installed they must be installed after the WindFarm program.

During installation you will be asked to confirm two file locations (if updating make sure you use the same location to which WindFarm is already installed):

Program files :

The default is C:\Program Files\ReSoft\WindFarmR4


The executables and help files will be stored here



Data files :

The default is C:\WindFarmR4


This forms the base directory for future projects and the sample case is installed in the sub-folder .\TURH along with wind turbine data in .\WTDB and tutorials in .\TUTORIAL.

Installation is straightforward and it is recommended that the default file locations be used (please avoid using "My Documents"). Now download and install the latest HASP driver.


This release of WindFarm is for Windows XP/Vista/W7/W8/W10 and uses a hardware security device called ‘HASP’. This has to be removed during the installation process, but attached to your USB port in order to run WindFarm. Use of the HASP allows you to install WindFarm on more than one computer (within your company and country), but only one computer can run WindFarm at any given time.

You now need to download and install the HASP device driver from the HASP Information page. When it has been installed re-boot your computer and set XP SP2 compatibility mode for WindFarm on Windows Vista, 7,  8, 10

You can then start WindFarm from Start->All Programs->WindFarm Release 4.
