    Everytime I try and download 4.2 it just keeps telling me its corrupted. If I use chrome, after its done downloading it just pops up and says the download failed because it was corrupted. I used IE and it says the same thing. I restarted pc, disabled Virus protection and retried. Same thing. What is going on here? I've got the live training tonight and want to be able to use the 4.2 to follow along. Please someone help me. If there is any other information that I need to give you please advise. Thank you and cheers!

    All I can say is that the download worked fine for me, using IE. Try clearing your browser cache maybe? Hard to say.

    Its exact wording states - The signature of UnitySetup-4.2.0.exe is corrupt or invalid. This is what it keeps telling me no matter what I do.

    It also upon trying to install states - Installer integrity check has failed. Common causes include incomplete download and damaged media. Contact the installer's author to obtain a new copy. WTF is going on here.

    Maybe some PC users can report the filesize in bytes of the installer they downloaded. These issues are usually incomplete downloads, or corrupted downloads. Can sometimes happen when one of our content delivery network servers caches a corrupted version. Knowing where in the world people who have problems are can help us track down which server is responsible.

    Your CDN really appears to be dropping the ball. I'm getting 50 KB/s download speeds on a connection that easily manages 2 MB/s under normal circumstances.

    As an aside, the download link for 4.2 on the archive page is broken. Someone forgot the minor (".0") part of the download URL. I tried manually fixing this and downloading using that URL, but despite being located a different subdomain, it delivered the same atrociously slow download speed, and I assume they're actually aliases for the same resource.

    EDIT: I forgot to mention, since you asked for geographical location, it's NW USA.

    ive tried to download 4.2 numerous times. each time the results are the same, corrupt download. ive tried with all major browsers and with and without use of a download manager. still the results are the same corrupt download. i have a very nice download manager that i can set to repeatedly download until some specified md4, sha1 checksum matches, but sadly unity3d website does not give me this information for the download. so i' stuck to download it, manually try to open it, delete it and retry the download. now imagine doing this for over an hour. honestly they should have some mirrors, give a checksum and make sure this does not continue to happen.

    I'm confused, what is a md5 and how do you use it to download unity? Thanks.

    MD5 is a simpe hash (unique number that identify a colleciton of bytes), if your downloaded file has a different md5 probably it is corrupted.

    What Im did was donwload multiples times until it get the same hash. For linux users, something like it:

    Code (csharp):
    1. while [ $(md5sum UnitySetup-4.2.0.exe) -ne cae1cb8a5d492fe997a2bcfb6bd1d3dc ]; do rm UnitySetup-4.2.0.exe; wget http://.../UnitySetup-4.2.0.exe; done

    I disabled my avg retried over and over again until I finally got a working copy. It literally took me a day or two of trying for it to work. Cincinnati, Ohio for me btw if you couldn't tell by my profile. All I can say to you guys is keep trying, and I been through your pain.

    Just do this guys, and it will work with any download you make:

    To bypass the corruption test, pass /NCRC on the command line. To do so, go to Start->Run, type cmd and hit Enter. A black console window should open. Drag the installer into the window, hit Space and type /NCRC. Hit Enter again and the installer should start.

    bypassing the corruption test is a bad idea (unless you want to install corrupt files).. the corruption test is there for a reason. If it fails the test, it means something is wrong. :)

    I am trying to download UnitySetup-4.3.4.exe and having the same issue.

    I am downloading http://netstorage.unity3d.com/unity/UnitySetup-4.3.4.exe, from South Africa

    Tried twice so far, on the third download now.

    Isn't there a non-dodgy torrent we can use to download these things? Much nicer solution for large install files like this.
