WiX unresolved reference to symbol media 1 in section fragment

Question

I am trying to build my WiX Project in Visual Studio 2010, but everytime I build, I receive the following error messages:

Unresolved reference to symbol 'Media1' in section 'Fragment:'

Unresolved reference to symbol 'Media1' in section 'Product{67DC7AE3-030F-4A24-AC3F-7AE7D0C32D07}'

The project includes one Product.wxs file and one heat-generated wxs someComponents.wxs (my fragment) file. I am referencing components in the heat-generated wxs file in Product.wxs. The sections where I am getting the errors are as follows:

Product.wxs file

If someone could point me in the right direction to resolve this issue--or maybe point out something I am missing--that would be greatly appreciated! Also please let me know if any additional information is needed to help answer this question, I try and provide as much information as possible.

Answer 1

The error message is trying say that you are missing a Media element with Id='1'. Usually, you'll find the Media element under the Product element. You just need to add something like:

<Media Id='1' />

You can then add other attributes to the Media element to compress your files into a cabinet. With later versions of the WiX toolset you can use the MediaTemplate element instead of the Media element to create multiple cabinets that do not exceed a certain size. That's great if you end up with lots of files.
