PSA: The installer for Alcohol 52% Free Edition 2.1.1.2201 attempts to install a piece of malware named BrightSDK. If you have a system which is giving you the "Loading Alcohol device drivers failed!" error after a system update, keep your old version and just extract the appropriate `SPTDinst.exe` or `SPTD2inst.exe` for your system from it using 7zip.
