I've been looking over the support forum for 7-Zip and all i found so far is that the download might be corrupted. Someone mentioned a corrupt file will give that message. I just downloaded it myself and had no problems.
I know some places don't recommend the use of download accelerators because you can get corrupt downloads. If you were using one, you'll have to try again without it. Otherwise i am still looking for possible explanations.
(make sure the file is being downloaded as a binary transfer)
