Kenneth,
How about using "codeBase" in the .config file?
e.g.
<configuration>
  <runtime>
    <assemblyBinding ...>
      <dependentAssembly>
        <assemblyIdentity name="A" publicKeyToken="xxxxxxxxx" />
        <codeBase version="1.0.0.0" href="file://c:\xyz\A2.dll" />
        ...

HTH,
Duncan Smart
