Do you know how it was installed on your system? Did you install it yourself or did it come bundled with some other software? Is it running smoothly or do you get some error message? Any information that will help to document this file is welcome. Thank you for your contributions.

I'm reading all new comments so don't hesitate to post a question about the file. If I don't have the answer perhaps another user can help you.
