2. Add a project reference to the WixUIExtension and add one of the standard dialog sets, such as WixUI_Minimal:

   <UIRef Id="WixUI_Minimal" />

3. On the Build page of the project's Properties, set the Cultures to build to "es-es".

4. Compile the .wxs file into an MSI and then remove the CAB file from the output directory.

5. Launch the installer...
