The <code>/silent</code> option for <code>iv_uninstall.exe</code> doesn't work. The remove process stops trying to display a window to confirm uninstall.
You can use <code>iv_uninstall.exe</code> from V4.25 to uninstall V4.27 silently. It worked for me.
Since V4.28 <code>iv_uninstall /silent</code> does work once again!
