    Something is wrong with the download file.

  • I was unable to duplicate the issue. The .zip archive extracted without error for me using 7-Zip.

    That error message can sometimes be indicative of a memory module problem, or even hard disk issues on occasion (as well as a host of other local machine related issues). Try downloading from a different machine and see if you can repeat the error.

    The download is working fine for me.

    Try a fresh download and reinstall.

    I downloaded twice.

    I uploaded 3.4.2 to my CentOS server with WHM/CPanel and if I extract using the File Manager, it is reporting corrupted CRC check error.

    I tried unzipping on my PC/Windows 7 with jZIP and jZIP is reporting “jZip does not support the file format of the file you are trying to open. The archive file could not be opened” I have an older version 3.4.1 and that file could be opened by jZIP.

    I uploaded the wordpress-3.4.2.tar.gz file as an alternative. It initially extract but then and I got this error message:

    gzip: stdin: invalid compressed data–crc error

    gzip: stdin: invalid compressed data–length error

    You don’t need an extractor when using Windows. You can just open the .zip archive like a folder and then copy the wordpress folder inside it.

    I get this error:
    “Windows cannot open the folder.
    The Compressed (zipped) Folder ‘…\wordpress-3.4.2.zip’ is invalid.

    Then there’s an issue with your local network or ISP. The download is working fine for everyone else. Try a different computer – preferably on a different network.

    IMPORTANT NOTE: When I used Firefox, I was having this problem.

    If I use Google Chrome, the download worked fine.

    I just downloaded both the .zip and the .tar.gz archives using Firefox 16, and both extracted as expected using the Windows native compression tools and 7-zip (for the .zip package), and 7-Zip for the .tar.gz package. No errors encountered.

    Ditto. Plus no other reports of corrupt downloads on these forums. So this has to be a local network or browser issue.
