Wix doesn't include any of the files in the .MSI - wix

Question

i am trying to add files in my WIX installer, however it doesn't do that at the moment. i am staring at it for hours now and i just can't see what might be the problem. the referencing seems to work alright as well as the target location. the installer runs fine up to the point when it needs to install files of course.

the ComponentGroupRef's and the Fragments they are connected to are currently not yet in use and dont have an impact on the program (the Fragments are left out of this example)
can anybody see what i might have done wrong or what is missing?
thanks in advance,

Answer 1

i have solved the errors. it had a conflict with my reference file i still had in the project, because of that it did see it as two references to the same symbol that i declared the way heavyd suggested.
thanks for the support Heavyd.
