1-Wire Drivers (Vista and x64 Support Now Available!)
The 1-Wire Drivers installation package installs the drivers and demo software for all iButtons and 1-Wire devices. Two application programmer interfaces (APIs) are made available through this package: the TMEX API and the 1-Wire API (based on the 1-Wire API for Java™) for the .NET framework. The 1-Wire Drivers installation package also contains the necessary low level device drivers and support libraries for the 1-Wire adapters available from Maxim. The current 4.01 releases of 1-Wire Drivers supports the following 32-bit and 64-bit versions of Microsoft Windows: Windows 2008 (future), Windows Vista, Windows 2003, and Windows XP. 64-bit 1-Wire applications will be made available for download when they are ready from the 1-Wire/iButton Software Search Engine. For support on Microsoft operating systems not listed, see an earlier 1-Wire Drivers download, such as version 4.00 or below.

Online Documentation
OneWireViewer
With the 1-Wire Drivers installations for Windows you get the OneWireViewer. The OneWireViewer is an application for exploring iButton/1-Wire features from your PC. Before using the program, you need only connect a USB port kit (DS9490R + DS1402D-DR8), or similar (serial port or parallel port kit) to your PC. The OneWireViewer automatically finds iButtons or 1-Wire chips on your system and displays their serial numbers with a description of relevant features and menu options. As the iButton and 1-Wire chip family grows, the capabilities of the OneWireViewer will be expanded to include the new devices.
The OneWireViewer is now integrated with version 4.01 and above 1-Wire Drivers installation. Although we package the OneWireViewer as an executable, a Java Runtime Environment (JRE) is still necessary for the program to run. The correct 32-bit JRE is available to be downloaded from http://www.java.com. The correct x64 JRE is available directly from Sun here: http://java.sun.com. The OneWireViewer was written entirely in Java, and can be optionally downloaded and installed as a Web Start application from the OneWireViewer page. Also available for download is the OneWireViewer User's Guide.
Alternate 1-Wire Drivers Packages
The following download links present the 1-Wire Drivers in different packages. These packages are primarily aimed at the 1-Wire software developer.
Download Version 4.01 Beta Releases (alternate 1-Wire Drivers packages)
Download Version 4.00 (alternate 1-Wire Drivers packages)
*The "bootstrap loader" is for those machines that do not have a Microsoft OS installed containing the Microsoft Installer runtime (comes natively with Windows 2000 and Windows XP or as an upgrade with other operating systems). When run, this install will detect the lack of the Microsoft Installer and load it first, then run the 1-Wire Drivers installation.
Warning: The COM object is no longer published nor supported by Maxim due to the lack of availability of the Microsoft Java Virtual Machine (MSJVM). Do not install the COM object if you do not have the MSJVM installed on your system. To avoid installing the COM object, make sure it is de-selected when prompted during the installation process.

The following are links to legacy 1-Wire Drivers installations (formerly known as iButton-TMEX).
