title: .Net Framework 1.1 on IIS 7.5 (Windows 7-64 bit)
body: <p>I'm in a situation where i will need to get my .Net 1.1 codebase setup in Windows 7, 64 bit machine that has IIS 7.5.</p>
  
  <p>I tried all possible blog posts including:<br>
  <a href="https://stackoverflow.com/questions/4502081/net-framework-1-1-on-iis-7">.NET Framework 1.1 on IIS 7</a>, 
  <a href="https://stackoverflow.com/questions/5940082/using-dot-net-1-1-on-iis-7-5-windows-7-32-bit">using dot net 1.1 on IIS 7.5 (windows 7 - 32 bit)</a>,

  <p>and a lot many out of google search.  But nothing worked.  Am I doing something wrong here? </p>
  
  <p>I installed framework correctly, had a couple of reboot too as prompted.  But .Net Framework 1.1 is not listed as an option in the drop down at all.  </p>
  
  <p><strong>Here is the screen shot.</strong></p>

  <p><strong>First part:</strong> ISAPI and CGI restrictions: shows up the dll correctly.<br>
  <strong>Second part:</strong> Even in the app pool, ASP.NET 1.1 got created with the steps i followed but the framework version selection doesn't contain 1.1</p>
  
  <p><strong>Here is the screen shot of my %windir%</strong></p>

  <p>Any help is greatly appreciated.</p>
  
  <p><strong><em>Update</em></strong></p>
  
  <p>I could setup the code base but this is a new problem now.  While trying to debug from VS 2010, getting the below message. Any idea?</p>
  
  <p>IDE: VS 2010 Professional</p>
  
  <p>IIS: 7.5</p>

  <p>OK.  After a long struggle, I installed VS 2010 on my old XP machine and re-built the application there itself and then moved the source code back to Windows 7.  No Framework 1.1 anymore.  It's now mapped to 4.0 (VS project conversion)</p>
  
  <p>Installed Debug Diag and that resulted in this message finally.</p>
