Steps:
1. After being stuck installing, try manually restarting your computer (e.g. press & hold the power button until PC turns off and then start again) and boot into Windows normally. If you can log into Windows normally without Windows freezing or crashing, proceed to step 2. Otherwise, see Step 1.a.
1.A. If, like me, Windows hangs when you boot it up after installing, try to restart the computer a couple of times until Windows will fail to load and you get into the advanced restart screen. Shouldn't take long after a few restarts. Otherwise, if you're luck or quick enough, login to Windows normally and press Start > Power > <hold Shift> while clicking Restart so you can get into Advanced Startup. Once you get to Advanced Startup, choose 4 (Safe Mode only)
2. Once in Safe Mode, you'll need to do two things:
2.A. Go to Control Panel > Programs & Features. Uninstall any AMD related content. If, like me, you get an error during uninstallation, that's fine. Proceed to 2.B.
2.B. Run the AMD DDU (AMD Cleanup Utility) and let it work it's magic. It should go through without problems (if you get some errors, I can't help you there since I didn't experience it). Once uninstalled, you can try to proceed to 2.C. (which was what I saw as the solution in other forums, but it didn't work for me. Nonetheless, try it first before proceeding to Step 3 as I did). If you fail at 2.C., proceed to Step 3.
2.C. Still in Safe mode, try to run the Offline Standalone Installer Wizard. Mine failed, but if it works for you at this point ignore the rest of the steps. You're one lucky guy. If you're an unlucky dude, see more below.
3. If, like me, you failed to install it in Safe Mode using the install wizard, run the Device Manager in normal Windows mode. At this point, make sure that Windows shows your driver as a generic driver or unknown video driver. This is your clue that your drivers uninstalled successfully and completely.
3.A. Right-click > Update Driver > Browse my computer for driver software > {your AMD driver location. Default is C:\AMD\Win10-64Bit-Radeon-Software-Adrenalin-2019-Edition-19.9.3-Sep30}
3.B. Cross your fingers it installs. If, like me, it installed successfully, you're almost done! At this point, the driver installed but not yet the CCC. So, proceed to Step 4.
4. Go to C:\Program Files\AMD\CCC2\Install (Default directory). Load-up the ccc2_install file. It should run without a hitch.
5. Check back to your C:\AMD folder and there should magically be a WU-CCC2 folder there. Double-click > ccc2_install and run the WULaunchApp. It should install without a hitch. My computer froze for like a full 5 seconds before coming back alive again. Just saying it in case you experience it. Next, if you click Start, you'll see the AMD Settings installed.
6. Restart again to normal Windows for safe measure, but now you should be able to run the CCC. Check your settings there and it should be the version you installed.
That's it! Crossing my fingers and I'm going to try gaming for a few days to see if it acts up. If I try to update it using the CCC, it says I'm already on the latest version (as of this posting). Good luck, and happy installing.
Hi. I was facing a similar freeze issue while installing Adrenalin 2019 Edition 19.9.2 (WHQL) (File Size,415 MB,Release Date,9/23/2019) driver for my Lenovo G500 laptop that has AMD radeon 8570 graphics card (2GB). The installation used to stop at 37 percent and the entire laptop process froze. I booted in safe mode, then ran AMD cleanup utility.
Then i booted in normal mode.
I clicked on the generic driver (showing as video controller) with a yellow exclamation mark in the device manager list and followed your process. The installation went smoothly, and after finish, I got the message, windows updated the driver succesfully. Immediately after that my laptop froze. I kept waiting for 30 minutes or so after which I forced shut down my computer. Then I restarted my computer. Now I am getting the same generic driver in my device manager list.
Is the driver still not installed? Moroever, there is no CCC2 folder in my C:\Program Files\AMD install directory.
What should I do now?
I suppose this item with exclamation is my radeon card.
Tat's my note details.
