IIS 8.5 displays 404 error when accessing .cfr pages.

Hello -

We have recently migrated about a dozen sites to a new server running Windows Server 2012 R2 and ColdFusion 11.  Everything seems to be working correctly except for .cfr pages.  IIS throws a generic 404 when attempting to access pages with this extension.  We have the Jakarta virtual directory setup correctly and our file mappings also look to be correct.  Allowing the app pool to run 32-bit applications changes the error from a 404 to an internal server error 500.  Any ideas?  Thank you!
