How to Install World Clock Silently
You can silently install Anuko World Clock by using the "/S" command-line switch (without quotes) when running the installer. Notice that it is a capital S. For example:
world_clock_full.exe /S
The "/S" switch suppresses all user interface windows during installation. The same switch will work for the uninstall procedure in case you need to uninstall silently.
uninstall.exe /S
Uninstall.exe is the binary file that the installer creates in the installation directory to uninstall World Clock when necessary.
