Strange things happens with the validation process. After my application has been validated i receive an email from "iadp-validation@intel.com" - "your application is not validated, hurry up, resubmit your application etc.". On the dashboard status of my application is "published". Please, anybody explain me what happens?
Yes, it means that your app has failed the updated validation methods. Now that Intel has a beta of the App Store to use as a validation tool, some MSI installation problems have been discovered. See the PDF that came with the email you are referring to, and see my post that may help as well:
