# Installing the HTML Help compiler on Windows

1. Enter the URL: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/htmlhelp/html/hwMicrosoftHTMLHelpDownloads.asp
2. From the MSDN page, scroll to find the heading HTML Help Workshop.
3. Select Download Htmlhelp.exe.
4. Click Run and navigate to a C:\ directory as C:\Program Files\HTML Help Workshop.
5. Follow the steps in the HTML Help install guide wizard to complete the installation.

If you install the Help compiler to a drive other than the C: drive, you may need to customize the <property> value for hhc.dir in some of the build .xml scripts in the Toolkit root directory. The Toolkit assumes the compiler is installed on your C: drive.
