I want to build an MSI installer of a JavaFx application with Ant

Question

I have developed a JavaFx application and it runs well without any problem. Now I want to build an MSI installer from it and I have modified build.fxbuild and build.xml. I have installed WIX tools also. When I run build.xml as an ant build it says build successful, but some error occurs and the MSI is not generated.

Error

Bundler MSI Installer skipped because of a configuration problem: Can not find WiX tools (light.exe, candle.exe).

  
Advice to fix:   Download WiX 3.0 or later from http://wix.sf.net and add it to the PATH.

BUILD SUCCESSFUL
Total time: 5 seconds

Above error occurs though I have included WIX into the environment path.
