Blu-ray Error: "Fatal Error", Code: "6", Note:''

I've run into this error a couple of times now...

The current wisdom is to install MSXML 6.0. I was going to try that, but when I went to install 6.0 the installer came back saying that I had a newer version of msxml installed and that I need to uninstall it if I want to install 6.0.

Is this something I should consider doing?

Thanks
