I have been trying to install inventor 2015 on my laptop it has more then the recommended requirements. it keeps failing from what i can tell it is during the installation of the low res image library im am going to attach the instllation log. Also I have tried installing other versions of inventor and also maya and the same happens. really needs some help any input welcome.
The errors you are getting are around problems downloading files, try downloading using the virtual agent instead.
Thanks,
Danny
