Exparamental help?

how does one install the exparamental? When I get it frome the front page, I download the file in the link, all 5ish mb, but when I open it to install I get a end of archive error? Help??

I urn into that problem quite often - the download terminates early. Keep redownloading it until you can open the file.

Yeah, it’s usually a problem where your internet connection decided to terminate the download early.
