I've run the installation routine and added the File Properties task in. I drag it out to my design surface, but cannot use it. I get an error that the component is not registered for use on this computer.
I assume so, I downloaded it on the 11th. Doesn't matter at this point. I figured out how to do what I needed using a Script Task and the component didn't give me the one file attribute I really needed anyway - the file size.
