Error 1603 is usually some sort of local system issue. Try the suggestions mentioned here if you have not already.Tried installing the latest drivers as I was having issues in Horizon Zero Dawn on my 5700XT. Had issues enough installing those previous drivers, kick off the install of the 22.4.1 driver.... and it failed again. Download the driver manually rather than letting it auto update, again the same 1603 general error during installation. Have had more issues with AMD drivers in the past month than I did for years of using Nvidia, so frustrating.
