title: Missing Eyeshot register in the toolbox
body: <p>I'm using Visual Studio 2017 and 2019 at this time.
  After Installation of Eyeshot Pro 2021 there is no entries in the toolbox.
  The strange thing is, that a manual insert does'nt work.
  If I rename a register in Eyeshot Professional 2021 there is mentioned that the register allready exists.</p>
  <p>So, how can I get the controls into my toolbox.</p>
  <p>Regards Jürgen</p>
