Chrome – Opening local document files in Google Docs

To disable Chrome from automatically using the Google Reader, go to "chrome://plugins/". Then locate and disable the plugin called "Chrome PDF Viewer". When this was installed, it should have automatically disabled your previous reader, (mine happend to be Adobe Acrobat, but this should work anyway). Then find your Foxit Reader Plugin entry, and re-enable that. Should work as soon as you load a PDF. You might want to restart Chrome to make sure, but for me it worked simply with a new tab.

Copying the document is your only option. See here and here. I cannot find more recent posts concerning this matter, and it would be better if you post a thread on the same forum.
