This error can also occur after a Windows 10 update if certain DLLs that you're using have been deregistered somehow. This is now the third time this has happened - and it causes normally fine CPU settings to appear broken.

Quick steps:

• Open developer command prompt for visual studio (as administrator)
• Run gacutil /l | find "Microsoft.mshtml"
• Go to the folder C:\Windows\assembly\GAC\Microsoft.mshtml
• Run dir and change to the directory
• Run regasm Microsoft.mshtml.dll
• Try to compile again
