Click this link to see if you have Microsoft .NET Framework Version 1.1 installed on the system where you are clicking this link.

If you have the .NET 1.1 installed, you should see a message “.NET Framework Installed”.
After you check this, you can create a test.aspx file containing one line:
<% Response.Write("Testing") %>
in your application folder (e.g., MyApp) and then access it through the browser to see if ASPX is correctly installed. To run this from the browser, enter:
http://localhost/MyApp/test.aspx
If you see the word “Testing”, then everything is set up properly. On the other hand, you might see the actual code from the file:
<% Response.Write("Testing") %>
In this case, your IIS server is not configured to run ASPX properly. Since Microsoft .NET Framework Version 1.1 is already installed, you may need to configure it properly.
