I was trying to install MySQL Community Server for Windows 10 using the standard .MSI installer provded from the MySQL website and the installer just hung, saying that there was 3 seconds remaining.
About half an hour later, it still said “3 seconds remaining”.
It turned out that you have to run cmd (commandline) as Administrator:
Press Windows Key (Super), type “cmd”, right click on “Command Prompt” and select “Run as administrator”.
Once this is done, “cd” to your location that you downloaded the .MSI to.
Once you are in the right directory, run the “msiexec” commandline tool with option “/i” as follows:
msiexec /i mysql-installer-community-126.96.36.199.msi
(Obviously replace the filename with the version you downloaded)
Once this runs, it will go straight into the Installer as you originally expected!
