Unable to compile downloaded binaries when executing elm-test

I cannot run my unit tests via the command line:

elm-test

      

        
        
        
      

    

PS C: \ my_path \ client> elm-test Download binaries from https://dl.bintray.com/elmlang/elm-test/0.18.6/win32-x64.tar.gz Compile error C: \ my_path \ client \ elm material \ generated code \ community elm \ elm test \ src \ Mainc5862d6 a0878fab784555034eda0ebc7.elm

Note: I'm not sure if this is a bug in the package or if it is under my control.
