I am having this same problem, I re-downloaded the files and the same thing happens the error occurs:
\"NSIS ERROR
Installer incorrupt or incomplete.
This could be the result of a failed download or corruption from a virus.
If desperate, try the /NCRC command line switch
(NOT recommended)\"
and i tried the md5sum application it just opens then closes with nothing in the window but a blank black screen (how do you use it?)
anyone know what the problem could be? thx
EDIT: nvm i think i didnt let the reassembler finish lol dummy > me
