unable to install radeon pro software on vega frontier with "driver option"

DO you have one or two Vega FE cards installed?

***Before starting make sure you have the year end 17.12.1 driver downloaded from here (The second driver option, not the 17.Q4 driver)  Radeon Pro Software and make sure you have Display Driver uninstaller downloaded and save to your desktop. You can grab the latest from here Display Driver Uninstaller (DDU) V17.0.8.1 Released. - Wagnardsoft Forum ***

Step 1: Boot WIndows 10 into safe mode and run the DDU utility and completely clean your system of all AMD drivers (Choose Clean and shutdown) *If you have an AMD CPU in addition to you VegaFE cards, DDU will clean your computer of the CPU drivers...make sure you have the latest AMD chipset driver if this is the case, if not you can ignore this step.*

Step 2: After your machine is turned off, open your case and take out the second AMD Vega FE card and leave it off to the side and turn your computer back on.

Step 3: Once you power your machine back on and you are logged in you can install the 17.12.1 Pro driver that I provided in the link earlier in this post and install it with the CUSTOM option. You will be prompted to install a gaming driver later on, choose yes and let the pro driver install. It may or may not ask for a reboot...reboot it.

Step 4: After your reboot launch the AMD Radeon Settings utility. The blue pro driver version will come up. Look in the lower left hand corner of the settings and you should see driver options. CLick it and choose "switch driver mode" It will ask to install the gaming version of the 17.12.1 driver. Choose "Install and switch mode" Your screen will go blank during this time. Allow the driver to install and when it is finished, the gaming driver will be installed. Make sure you shutdown your machine after this.

Step 5: Once your machine is powered down go ahead and put your second card back into your machine and power it back on. Login to your account and bring up the radeon settings again. It will be back to the pro driver...not to worry. Go into the driver options in the lower left hand corner and switch the driver mode from the pro version to the gaming version. This will take 5-10 mins. It will look like your machine is hung....just leave it alone. Your screen will flicker 8-10 times...this is normal. Just let it do its thing, go and grab a cup of coffee.Once the machine flickers and is finished the radeon settings will come back up in gaming mode.

Step 6: In radeon settings, click on the gaming tab and global settings. Look for Crossfire to be enabled at this point. Try your games in crossfire that you want to play. You can monitor if your second card is being utilized or not with a utility such as GPUZ ot MSI afterburner. It has been hit or miss with Crossfire for me. Firestrike works in crossfire but Battlefield 1 and 4 will not work in Crossfire. AMD still has some work to do.

It is important that you follow these steps to the letter, if you don't Crossfire won't work.

Good luck and let me know how it goes.
