Jira Data Center Failure to load. tcnative-2.dll can't load IA 32 bit .dll

[Scott Haase]

After unzipping the install into the Jira startup directory I created I can't start Jira I get the message "The error reported was [C:\jira\bin\tcnative-2.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform]. 

There isn't a 64 bit version included in the download so I went over to Tomcat and downloaded the 64 bit version of tcnative-2.dll but when I try to register the .dll I get the module entry point wasn't found and to verify the .dll.  Where can i get the correct dll?
