Need help with Side-by-Side Assembly on Vista

I have a COM dll that I am distributing as a Side-by-Side reg-free dll.
On XP I have no problems using the component, on Vista I get errors trying
to create the COM object.

Either 0x80040154 (Class not registered) when using a GUID to create the
object or
0x800401F3 when trying to use the prog id.

Is there something additional that needs to be done to get Side-By-Side
assemblies to work on Vista?

The dll manifest is embedded in the dll

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity name="MyAssembly" version="1.0.0.1" type="win32"
processorArchitecture="x86"/>
<file name="MyDll.dll">
<comClass clsid="{EAFAB8C6-6DA1-453C-BEEB-6DB54F574FE0}"
description="My Class"
tlbid="{10FE49AF-15C5-4FAB-8AB8-0FA72A0A43F9}"
threadingModel="both"
progid="MyDll.MyClass.1">
<progid>MyDll.MyClass</progid>
</comClass>
<typelib tlbid="{10FE49AF-15C5-4FAB-8AB8-0FA72A0A43F9}"

</file>

proxyStubClsid32="{EAFAB8C6-6DA1-453C-BEEB-6DB54F574FE0}"
numMethods="13"/>
</assembly>

You'll probably find more resources and better help with this at MSDN:
