An MSI file is like an EXE file, and if it's saying it's corrupt that's probably is, download a new install distribution. I usually download the full thing rather than the install from the Internet style download.

You're installing in your directory, so you should be fine.
I'd try a full un-install then manually delete that file it is indicating if it is still there.

Try redownloading the file , directly from sun.com. If you get the same error, you could try downloading a older version or a version of Java SDK ( which includes the JRE ).
