This guide tells you how to install and configure DP4 for 32-bit and 64-bit Microsoft Windows. If you are installing 4.621 or a later release of DP4 on a machine with DP4 already installed and you use the DP4 installation program then you do not really need to read this guide, because the installation program will preserve existing information when you install a new release of DP4 over your existing installation.
Please check the Requirements page before attempting to install DP4.
If you are installing on a 64-bit version of Windows or on a version of Windows later than Windows XP then check the Platform Specific Considerations page before attempting to install DP4.
This guide does not cover installing DP4 on Windows CE devices. Please refer to DP4 for Windows CE, on the Itim DP4 Web site for information about installing DP4 on Windows CE.
In release 4.621 there were a number of changes to DP4 installation. You can read a summary of the changes in Changes to DP4 Installation for release 4.621.
