title: Error using x86 NAnt Custom Task on 64bit machine
body: <p>I have written a NAnt custom task in C# to clean out a set of tables in an Access database. This was all working fine for years on my 32 bit Windows machine. Now I'm on a Windows 7 64 bit box and here the troubles start.
  To avoid problems accessing an Access database from a 64 bit process I've set the build target for my custom task from AnyCPU to x86 (check: <a href="http://social.msdn.microsoft.com/Forums/en-US/ce9f68ae-5abf-4070-8a37-e3cc839dd13f/accessing-a-mdb-database-in-64-bit-platform?forum=netfx64bit" rel="nofollow">Accessing a .mdb database in 64 Bit Platform</a>). But know NAnt seems to be unable to load the custom task => <code>Invalid element &lt;CleanOutAccessDB&gt;. Unknown task or datatype.</code> (I've double checked that the custom task dll is in the NAnt bin folder).  </p>
  
  <p>Any ideas how I can run a x86 custom task with NAnt on a 64 bit machine?</p>
