Meinberg provides a secure and easy-to-use installer for NTP which allows everybody to install the stable version of the reference implementation of NTP as provided by www.ntp.org in cooperation with the NTP Public Services Project. The installer can be used on all systems running a Microsoft Windows Operating system (starting with Windows NT SP6a).
A simple automatic update mechanism optionally allows to simply replace the binaries of an installed NTP version. This is detected when the installer starts and can be safely selected for 4.2.4p7 installations. Older NTP versions should be removed before the new NTP 4.2.4p8 version is installed. Uninstalling the existing version can be performed by the installer as well and will be offered if the user does not want to use the simple binaries replacement approach.
The original announcement of the new NTP version has been published as follows:
