You have more than one problem (apparently) related to mixing 32 and 64 bit binaries. You don't state what you would like to have as a binary, 32 or 64 bit, but you should decide and then verify that all your to be linked in libraries are all in that bitness.

Then I suggest you just create a new project from scratch (copy the source files from the old project into the new project), respecting the bitness. i.e. choose Win32 or x64 from the pull-down menu at the top of the IDE.

This seems a bit drastic, but you'll save yourself the trouble of debugging your project (for a 5 minute job). Once you've got a working project I suggest you create a project template from that, so in the future a new project can be generated from that template (in seconds). Just do the google or checkout f.e. this or this (just some results that popped up doing some duckin).

Hope that helps,
