title: ASP.NET: "Could not find installable ISAM" exception when trying to read dBASE IV file
body: <p>I need to open and read a Dbase file in my ASP.NET application. When I try to open the connection, I am getting the exception "Could not find installable ISAM." I have tried the solutions in the top answer in <a href="https://stackoverflow.com/questions/512143/error-could-not-find-installable-isam">this question</a>, but they did not work for me.</p>
  
  <p>The filepath of the data file is C:\dev\DATA.DBF. Here is the code I am using to try to open the connection:</p>
  
  <pre><code>Dim connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;DataSource=C:\dev\DATA.DBF;Extended Properties=dBASE IV;"
  Dim connection As OleDbConnection = New OleDbConnection(connectionString)
  connection.Open()
  </code></pre>
  
  <p>At this point I get the exception "Could not find installable ISAM." Do you have any ideas what I can try to get this to work? Note that I am able to import this file into an Access database as a dBASE IV file.</p>
  
  <p>I am running Visual Studio 2008 on Windows 7. Let me know if you need any more information. Thanks for your help.</p>
