Ember broccoli plugin symlink exists error

I am getting an error when running ember s in Windows, same project works on Linux.

The Broccoli Plugin: [object Object] failed with:
Error: EEXIST: file already exists, symlink 'C:\ClientUI\public\assets\chart' ->

The broccoli plugin was instantiated at:
undefined

How can I solve this problem? Thanks
