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 deselected when prompted during the installation process.
*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.
