Hello, the problem looks like it is happening when you have copied the same two libraries with the same name in two different Arduino folders. My suggestion is to manually delete all library files from C:\Users\erikj\Documents\Arduino\libraries. Then you compile it again, and according to the error prompt the missing libraries are then added to the libraries directory again. If the libraries are included in the on-board package, you don’t need to add the libraries to the libraries directory.
