I did the AMD Clean Uninstall Utility to remove display and audio drivers, then I downloaded the Crimson ReLive Edition 17.2.1, but I can't install this software, it stop always working while I'm trying to install.
I also disabled my antivirus and tried to download other versions, like the 17.3.3 and the Minimal Setup, but I had the same problem.
AMD R9 270
Windos 10 64bit Education
I would recommend fully updating Windows, including all optional updates. Download DDU and use that to remove your current AMD driver, then download the latest Crimson driver and see if you can extract the package successfully.
