Error to deploy a silverlight application in IIS6: Invalid or malformed application: Check manifest

Folks, I deploy a silverlight application on windows server 2008 (IIS7) and ran ok, no errors.

I put this same application on another server with windows server 2003, IIS 6, with the mime types开发者_如何学Python configured, asp.net 4, etc. But when I try to run it I get the error: Invalid or malformed application: Check manifest

I checked on google, but the attempts were unsuccessful. Anyone out there have any idea what might be?
