A bit disappointing. I don't know why this seems to happen at exactly same place when installing Zorin at: ACER aspire ONE 1 GB RAM Intel Atom uP N450. I had to switch to xubuntu ( much slower OS but installation process works flawlessly ).
When I install Zorin 15.3 Light 64 bit it stops/freezes at the same place where one registers name password and computer name. I have tried 3 times now, fresh installation with new partition table each time, same spot, it stops/freezes when registering name and password. I would love to make it work.
