If you built a DLL via py2exe and registered that, then it will not be 
using the local installation of Python but a copy of Python which py2exe 
has packaged up.  That is basically the entire point of py2exe.

A py2exe created package does not need Python installed to work. 
However, it also doesn't perform the actual installation - you want 
something like nsis or inno for that.

I have heard that internet explorer can get upset with the installation 
files for some reason - can you try a different browser?  Or even try 
and start the installer executable from Windows itself instead of via 
IE?  FWIW, the files on sourceforge are fine.

The files are hosted on sourceforge and they often redirect you to a 
mirror.  I'm afraid I'm not sure of what the canonical location of the 
"actual download" is, but I'd be very very surprised if one of their 
mirrors added a virus.
