Answer 1

Microsoft.mshtml.dll from PIA folder is not signed.
If you have signed project, you must take version from "Primary Interop Assemblies" folder.

To do that:

1. Remove reference to Microsoft.mshtml (if you have one in your project)

2. Click "Add Reference" and than DO NOT select "Extensions" but "Browse" and point to "C:\Program Files (x86)\Microsoft.NET\Primary Interop Assemblies" (for .64 bit Machines) - that version is signed.

3. Edit properties (select microsoft.mshtml reference and press F4) in order to set:

Embed Interop Types=false
Copy Local=true

4. Rebuild your project
