My installer is giving me a host of warnings and failing on an error
about a .licenses file:

ERROR: Could not find file 'c:\working\DM\Data Monitor\

The warnings don't seem to be a huge problem, but the error is fatal.
The file it seems to be referencing exists at the given location
(assuming those tokens are getting resolved to where I think they
are).  What's the deal here?
