Registering Event Log on Windows

Hi Guys,

I'm trying to register the event log on Windows ( Windows Server 2012
64-bit ) with the following command:
regsvr32.exe C:\PostgreSQL\pg96\lib\postgresql\pgevent.dll
and I'm recieving an error message:

The modoule "C:\PostgreSQL\pg96\lib\postgesql\pgevent.dll" was loaded but
the entry point DllRegisterServer was not found.
Make sure that "C:\PostgreSQL\pg96\lib\postgesql\pgevent.dll" is a valid
DLL or OCX file and then try again.

I tried several solutions but none of them was helpful, for example:
I ran the command with another version of pgevent.dll
I ran the command with regasm.exe

The PostgreSQL version is: PostgreSQL 9.6.4

Any ideas?

Thanks in advance,
Ronen
