I have a Canon Pixma MG3100 printer. Its software is downloaded on a Lenovo desktop computer, running Windows 7. I have recently purchased a Lenovo laptop computer which runs Windows 8.1. When I tried loading the printer's disc software to the new laptop, it stalls before loading the printer drivers and tells me that they are already in use. Then it tells me to turn off and start the process again. I have done this at least six times without success, the printer drivers haven't loaded and so the printer doesn't function with the laptop. Can anyone help me?
