IIRC, this means that the library wasn't linked with the /machine:x64

At home, I've been using x64 Windows 7 on trunk and haven't had any
problems.  At work, I've been using 1.52 with a similar command to yours,
except our scripts are calling bjam and not b2.

Have you verified that your project was built x64?

Have you tried doing just:

b2 --with-test
