Here are the most common issues when this error occurs. Make sure you check all of them.

Since you have already verified the framework and 64bit CPU I would strongly believe that you are running into permission issue.
Are you running ths console app right from Visual Studio i.e. Your VS 2010 is installed on SharePoint server and you are hitting F5. If that is the case then make sure you run your Visual Studio as System Administrator i.e. right click --> Run As an Administrator
If you are executing console app on the server then do the same thing with the Console App. Right Click and then Run as an Administrator. 
If that does not help make sure that account you are using have read permission on the site collection.
