I'm trying to use SRBMiner because I've heard good things about it.  But whenever I try to install Adrenalin 18.6.1 for my Vega64 the install crashes. 

While connecting the monitor to CPU integrated graphics, I've erased all drivers in the C:\AMD directory (except 18.6.1), DDU'd the system while in safe mode, disconnected from the internet, and tried the install.  After clicking "Agree & Install", it circles for about 3 revolutions then crashes and reboots.  Tried all sorts of shenanigans but couldn't get past that.

Any ideas please?!
