Crystal XI and ACCDB File?

Hi,

I am developing a web application which uses crystal XI for report viewing and an Access database. I found that I had to change the application pool to 32bit because my MDB file was 32 bit and the DAO does not support 64bit. I recently created a new database in Access 2010 and realised the file extension was accdb. Does this mean that Microsoft Access 2010 now supports 64bit and can I open this database in Crystal XI using 64bit technology?

Appologies if I have posted this in the wrong section but the end question is relating to opening and access 2010 database in Crystal XI.

Many thank for any help,

Jiggy
