As far as I have understand this happens only once. Because I did not understand fully the certification process for trusted application I do not care about that. So Windows has no key that it knows the application should be fine. I encounter this for some application that i got from the internet. But after i accept the application the warning windows will not shown again.
But this is a different issue than the missing xmpd.dll that happens here.
