I have been battling this all day since finishing isntallation. It crashes while authenticating 100% of the time with this error code.
-Updated GPU driver
-Optimized settings in GeForce for the heck of it
-Tried changing SC2 CPU affinity to use less cores
-Error says installation files are damaged, scan & repair says no files are damaged
-Tried running in x32 for the heck of it then changed it back to x64
-Tried running BNET as admin
-Tried running in full screen and full screen borderless
-I don’t really have the option to delete and reinstall, I am away from home and used up my hotspot data to download.
