title: An Error Occurred While Downloading A Required File
body: <p>I'm not sure if this is the right forum or not, since I have no idea what's causing this problem.  I have a WPF application that was compiled into a setup project.  After building the setup project, there are two files: setup.exe and [Program Name].msi.  I put both files in the same directory in an ASP.NET website, served via IIS 7.5.  Everything was working fine for about a week, until I started getting the error:</p>
  
  <blockquote>
    <p>"An error occured while downloading a
    required file.  You may retry
    downloading the file or cancel setup."</p>
  </blockquote>
  
  <p>This happens when I click on a link on my website for the setup.exe file.  After seeing this error, there's a tab labeled "Details" which I can click to display the message:</p>
  
  <blockquote>
    <p>"An error occurred trying to download
    '[website url for the .msi file]'. See
    the setup log file located at
    'C:\Users[username]\AppData\Local\Temp[some
    alphanumeric
    sequence].tmp\install.log' for more
    information."</p>
  </blockquote>
  
  <p>I looked at this file, but it just restates that there was a problem downloading the .msi file.  Can anyone offer me some suggestions?  I'm really stumped on this, and have no idea where to go...</p>
  
  <p>Many thanks for the help!</p>

  <p>EDIT:  This appears to be a problem with the computer that I'm downloading the program to.  I tried downloading and installing the program on a different computer, and everything worked fine.  Apparently, I must have changed some setting on my computer to cause this, although I'm not sure what that is...</p>
