latest update keeps failing to write to a file

Have tried several times to update free version ccleaner which has failed with the following message image.png.68dd9241545a85dc1e686a68900785d8.png.

I have tried ignoring but still fails, getting following msg - image.png.eb10e105f83af6aa1b59693d60a65d20.png. Have windows 10. Would appreciate any help

Thanks in anticipation.
