When I install Alcohol (Version 22.214.171.12412) on Windows 10 Build 18362 (Version 1903), it always shows an error at the last step of the installation:
As Alcohol has not been updated for several months since last year, I guess it would be a compatibility issue between Alcohol and Windows 10.
Please check and fix it ASAP.
Additionally, this tools caused BSOD (after reboot) on my laptop. Please check as well. If confirmed, stop using it because it can cause the Safe Mode BSOD.
