After moving into a new home... trying to get 5642 working again. Have downloaded EN5640_Full_WebPack_40.13.1176 but the install fails in step 1. Detail error says "error 5" and mentiones caller not in admin mode. Even though install instructions don't mention running install as admin, I tried that with same results.
Am I missing something here on how to install the printer? UPDATING WITH ADDITIONAL INFO - have tried this from 2 different computers with same results. ALSO - have done complete factory reset, reconnected to WIFI but still cannot print via network (is working via USB - see my reply for more details)
Thanks
