title: Invalid Resource File
body: <p>When attempting to compile my C# project, I get the following error:</p>
  
  <pre><code>'C:\Documents and Settings\Dan\Desktop\Rowdy Pixel\Apps\CleanerMenu\CleanerMenu\obj\Debug\CSC97.tmp' is not a valid Win32 resource file.
  </code></pre>
  
  <p>Having gone through many Google searches, I have determined that this is usually caused by a 256x256 image inside an icon used by the project. I've gone through all the icons and removed the 256x256 versions, but the error persists. Any ideas on how to get rid of this?</p>

  <p>@Mike: It showed up mysteriously one night. I've searched the csproj file, but there's no mention of a CSC97.tmp (I also checked the solution file, but I had no luck there either). In case it helps, I've posted the <a href="http://pastebin.com/mcd2607b" rel="noreferrer">contents of the csproj file on pastebin</a>.</p>
  
  <p>@Derek: No problem. Here's the compiler output.</p>

  <p>I have also uploaded the icon I am using. You can <a href="http://rowdypixel.com/tmp/CleanerMenu.ico" rel="noreferrer">view it here.</a></p>

  <p>@Mike: Thanks! After removing everything but the 32x32 image, everything worked great. Now I can go back and add the other sizes one-by-one to see which one is causing me grief. :)</p>
  
  <p>@Derek: Since I first got the error, I'd done a complete reinstall of Windows (and along with it, the SDK.) It wasn't the main reason for the reinstall, but I had a slim hope that it would fix the problem.</p>
  
  <p>Now if only I can figure out why it previously worked with all the other sizes...</p>
