AMD drivers can't get installed

[Sakis]

Hi i have been trying to install the 18.5.1 since yesterday

my system:

gpu r9 390 nitro

cpu amd fx8320e

ram 2x4gb gskill 2400

mb asus sabertooth 990fx r2.0

1x1tb toshiba and 1x160gb hitachi

windows 7 ultimate 64 bit

my driver before trying to update was 17.1.something which i don't remember

i got error 1603, i tried DDU in safe mode and tried again then i got generic error

i tried an older version of the drivers (17.12.1) always after DDU and again same problems

i also tried in uefi bios and not of the gpu (it has 2 as far as i know, it changes with a blue "S" led button)

edit: i forgot to mention i was always disconnected from network as i read it may help on 1603

Hit win+R, and enter services.msc, find Windows Installer, double click it, and see if it's stopped or started. If it's stopped, start it, if it's started, stop it and then start it again. Then hit win+R, and type in msiexec /regserver. 

 

Also make sure you're running it as an administrator, and double check your permissions to the drive. As error 1603 can be caused by both of these.

thanks but it didn't help, i am trying to run win updates which i had left on but when i checked today had an error, i fixed it and now i am updating, i hope it fixes it.
