installation - WiX installer fails with error code 2819

Question

I am trying to create an installer using WiX which doesn't show the license agreement at the start. But I get the error as below.

This is the full Product.wxs file I have at the moment. It compiles and builds OK. Why am I getting an error like this? Is my Fragment section in the right place? I have removed the Publish elements pertaining to license and modified the welcome dialog's next button to show the install directory dialog instead of license agreement. This is as mentioned in the help chm file. What am I missing then?

The edited version of the WiX file that gives no error. This version however skips the install feature and browse for the file dialog:

Removing that gets the following error in the MSI logs:

DEBUG: Error 2819:  Control Folder on dialog InstallDirDlg needs a property linked to it

Basically this means that the "browse for folder" control isn't linked up to an actual property value. You've used the value INSTALLLOCATION for the application folder - which in turn means you'll need to add the following value to link the dialog:

<Property Id="WIXUI_INSTALLDIR" Value="INSTALLLOCATION" />

Good luck!
