Of course that's the reason.

When ntpd is compiled with default configuration under Windows then also 
the crypto code is compiled in. Otherwise it wouldn't be possible to 
enable crypto at runtime via a configuration option.

If there is some code compiled in which calls openSSL crypto functions 
then the openSSL DLL needs to be available when the ntpd binary is 
loaded into memory. Otherwise you get an "unresolved symbol" popup error 
when you run ntpd on the command line.

A workaround for this would be to have ntpd import the openSSL functions 
dynamically at runtime, but probably the next version of the Meinberg 
installer will just not allow to deselect the openSSL component at 
install time.
