I think you are posting in the wrong thread, JimDot.
These are two completely different things (but with similar names and overlapping purposes):
- Source Code Viewer Plugin (The other viewer/editor, which uses the DLLs you mention and which will not work on 64-bit Windows.)
- Syntax coloured source-code viewer (32 & 64 bit) (This thread, which is about a different viewer which works fine on 64-bit Windows.)
