All downloads are listed here.
"Zip with executable" ist best for portable use of the application. "Last build" is the same, except that it is the newest build and bleeding edge, so it may contain new bugs also (use it only if you know what you are doing - also see here at the bottom). If streamWriter was installed, the installed files can be replaced by the files from the zip archives.
Moreover, all downloads are free of...
- ...viruses and trojans.
- ...other stuff like browser-toolbars etc.
