HTMLViewer renders a website incorrectly

I just tested the code above in a new vm install of windows 8.1 64bit mainly to see if there was any difference to Windows 10. As with my windows 10 tests it worked every time when casting to an Int32 using ctype with both a 32 and 64 bit exe’s (I manually deleted the registry entry after each run).

The code above looks good, it would be nice to get some feedback from others just to make sure.
