NSIS contains a full data check, however, if the installer is corrupted in such a way that Windows can't load it anymore, there is nothing that can be displayed.
My script is attached, although I am not sure how it will help.
I see what you mean about the data check; it does seem that the symbol table is being corrupted and preventing the installer from launching.
Would have thought by now that MS would get their act together on file downloads with IE... sigh.
