I think (but am not certain) the scannercopy.msi is part of a HP scanner installation package. Do you have a HP scanner? If so, is it possible for you to uninstall it temporarily, install CFP and then reinstll the scanner software.
I'm clutching at straws here and realise that this is a workaround rather than a solution, but the only real mentions I could find were in languages I can't speak.
Let us know if you are going to try this.
