XP/Vista ADOX References

I built a large application on XP and a tiny but needed component uses ADOX for table creation and persistance in an Access database.

I couldn't build the project on Vista until I deleted the ADOX reference and replaced it because msadox.dll has moved from Windows/System32 to Program Files\Common Files\System\ado.

If I wanted to support a single build on both operating systems am I going to have to resort to late binding

That's not an easy dll to late bind to.
