I don't know what the Meinberg installer does when installing the
binaries though I did provide some advice to them at the time. What you
do need need is to have the Change System Time privilege enabled for the
user account running the service. I believe that local service has that
or you set up an account that specifically includes that privilege. You
have to do that in the Local Security Policy MSC. Either that or have
administrator group. I advise not doing either of these but to establish
a separate account with that privilege and logon as service privilege
and remove it from the Users group.
Also make sure you disable Windows Time.

If it was built with VC90 then you need to have the freely available
VC90 runtime installed. You need OpenSSL as the Windows binary is always
built with it.

Is Windows Time running? If so you need to disable it.
