MSBuild: Most people use MSBuild - I believe - to build via the command line like that. There is a section on using MSBuild in the WiX help material.

Custom Action DLL: I include custom action DLLs from within the WiX source file. Here is a sample with hard coded paths in the WiX source file for how you can include your custom action dll:

The construct: $(env.SystemRoot) - in the WiX source below - gets the environment variable %SystemRoot% - which resolves to C:\ on most systems (to list environment variables open a cmd.exe and type set and press Enter). The below source should hence compile on all systems without modifications:

Batch Build: This should suffice, no need to specify anything in the candle.exe and light.exe commands to build the MSI. Here are some sample commands:

"%WIX%bin\candle.exe" product.wxs -ext WixUIExtension >> Build.log
"%WIX%bin\light.exe" -out Test.msi product.wixobj -ext WixUIExtension >> Build.log
