I downloaded 7.4.1 upgrade zip and upgraded a local copy of DNN with no problem. I then uploaded and extracted the upgrade on a live server to an almost bare install and again it worked ok. I then uploaded the same upgrade file to an install with a few child sites and the install wizard ran instead of the upgrade. I have restored the instance backup to wait and see if there are any ideas before trying again.
