How to run a 64 bit web application on a 64bit machine

Question

I have to make a web application as 64 bit [ Since i am using a dll with only 64 bit version exists]. And my machine config is 64 bit machine and in IIS Application pool settings Enable32BItApplications flag is false for all pools. But when i try to run my MVC3 project i am getting this exception

Parser Error
