Just googled a bit - and it seems that there's licensing involved with those libs -
(as well as .NET-interop-stuff etc.)

Though maybe it helps when you try to (re)register the license-keys properly?

If that doesn't help, then you will have to ask their tech-support - or try to
(find and) contact other users who use those libs.
