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 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?

  • Hey Daniel, thanks guy. My problem was that I was changing the file. xap directly, to change the port of ServiceReference.ClientConfig. I started to change the port before publishing the file .xap and error is over. Regards. – Eduardo Apr 26 '11 at 12:46

  • Subhash, I created a new project web with silverlight project. I have instaled it in a server with II7 and I have no errors, works fine. Now I need to run in a windows server 2003 with II6. I have configured mime types, asp.net 4, and etc. My service is working fine. What can be? – Eduardo Apr 20 '11 at 17:23
  • are you using asp.net security options like authentication/authorisation for the folders if so check permission for the clientbin folder – Subhash Lama Apr 20 '11 at 17:29
  • I got full permission to everyone on the application folder (include clientbin), but I got the same error. – Eduardo Apr 20 '11 at 17:46
