>As of Office 2010 there is a 64-bit version of Microsoft Access. If you Google [microsoft access 64-bit], one of the links is to a downloadable/redistributable Access Database Engine 2010 ( http://www.microsoft.com/en-ca/download/details.aspx?id=13255 ). The second link (x64) should be the 64-bit version.

Thank you, I have forwarded the information to the developer and requested a test with that 64 bit version combined with a compilation in 64 bits.
