If you want to generate compiled HTML files with DB Doc, you need to first install the HTML Help Compiler Workshop from Microsoft.  You can download the installation package from here:

Once installed, DB Doc will try to find the HTML Help compiler (hhc.exe) on your system and use it.  You can check if DB Doc has found the compiler by opening the Settings screen:

If DB Doc was unable to find the compiler, you will need to enter the name and path to the compiler manually.
