title: Running Oracle 11g r1 on Windows 7 x64 getting 64 bit error
body: <p>I have installed Oracle 11g r1 64 bit on Windows 7.  I am able to connect to it using Sql Developer and a command line tool written in .Net that is 32 bit.   I am using Visual Studio to create an ASP.Net application.  The solution has 4 projects all of which are compiling for "Any CPU"  I installed the 64 bit version of Oracle client and I keep getting the error below.  The project is using the System.Data.OracleClient provider.  Everything is 64 bit so I don't know why I am getting the error.</p>
  
  <p>[InvalidOperationException: Attempt to load Oracle client libraries threw BadImageFormatException.  This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed.] </p>
