When I clicked on the Utility icon the software failed to open giving an error message "Eos utility has stopped working. A problem caused the program to stop working correctly. Windows will close the problem and notify you if a solution is available" I uninstalled the utility program and reinstalled it but still get the same message. I have repeated this several times over several days but still the problem exists. I have used this software for months without any problems until now. Does anyone have a solution?</P> Thu, 14 Jan 2016 22:21:07 GMT https://community.usa.canon.com/t5/Camera-Software/EOS-Utility-software-not-opening/m-p/161794#M9442 Desmiddyac 2016-01-14T22:21:07Z https://community.usa.canon.com/t5/Camera-Software/EOS-Utility-software-not-opening/m-p/162025#M9443 You could try doing a system restore on the pc because likely there has been an update the software didn't like worth a shot Mon, 18 Jan 2016 02:30:36 GMT https://community.usa.canon.com/t5/Camera-Software/EOS-Utility-software-not-opening/m-p/162025#M9443 Blightyguy 2016-01-18T02:30:36Z
