On Windows you should run your cmd.exe or Powershell in Administrator Mode, then run AfterCodecs installer executable with the
/S
argument, for example in Powershell :
./"AfterCodecs v1.9.7 Installer.exe" /S
if you're in the extracted folder from the downloaded zip. Same goes for the uninstaller but you'll also need to specify the
-Uninstall_AfterCodecs
argument.
If you want to be sure that the installer / uninstaller exit automatically without user confirmation you should run the .exe like this instead
start "Autokroma" /wait /b "PathToInstallerOrUninstaller.exe" /S
