Need correct mysqlfrm command path to restore a database from .ibd and .frm files
You cannot just move the .exe around like that and expect it to work. All libraries and dll's (in your case I suspect _bz2.pyd) have to be in the same directory structure.

You can execute commands from other locations by specifying the entire path or from any directory which is in your PATH environment variable.

You could either execute 

C:\wamp\bin\mysql\mysql5.6.12\data\wordpress&gt;c:\path\to\mysqlfrm --server=root:rootpassword@localhost --port=3307


or change your PATH
