I tried to install 19.12.2 and 19.12.3 on my Laptop which has Intel Graphics and AMD Radeon HD8750M Graphics, both versions shows error 173.
Current Adrenalin Driver(19.11.13) shows 19.12.2 as the "New Recommended" driver, but when I try to install Error 173 emerges. same with the "New Optional" 19.12.3 driver.
