I have been trying to download the CS50 application, but this link (and also the torrent version) both return an error. Saving the link just gives a server error message in the download box.

Slicking to open the download link gives this error:

This XML file does not appear to have any style information associated with it. The document tree is shown below.

<Error> <Code>AccessDenied</Code> <Message>Access Denied</Message> <RequestId>4021A65640F1EC8C</RequestId> 
</HostId> </Error>

Am I missing something?

  • At last it's downloading! ^.^ Now waiting for the 2015 course to start as I dont have enough time to do the 2014 course (but I know a bit of what to expect, so should be fun!) Commented Dec 31, 2014 at 13:43

The link provided in the top post is not the most recent version of the appliance. You want the 2014 version not version 19, which is from the previous year.


  • When I first put the post up, I had just enrolled on the CS50 through edX that ended 31st December (had not realised at the time). I am now enrolled on the new one which as you say uses the 2014 version. But thanks for answering :) Commented Jan 2, 2015 at 10:38
