Copy libzmq.dll to C:\Windows\system32

This step is only required if libzmq.dll is not found in C:\Windows\system32.

To enable LogQueryService to get data from Data Indexers, you must copy libzmq.dll from the API installation directory to C:\Windows\system32. libzmq.dll can be found in the bin directory of the API installation directory, which is C:\LogRhythm\WebSiteRoot\LogRhythm.API\, by default.
