Sorry, I must be having a bit of a thick moment.

Are you saying that the ACE drivers can be used in an openrowset query in a x64 installation of SQL. If this is the case do you have some instructions on how to do this please? Everything I've read on the web seems to indicate that this is not possible and I have some clients that would be very pleased to see this functionality without having to have an additional x86 instance of SQL.
