Hi, I'm testing Nxlog EE trial. nxlog-trial-4.4.4347_windows_x64.msi

And configured nxlog on windows host, but om_kafka output module won't work. with error

2019-06-14 18:28:47 ERROR Failed to load module from C:\Program Files\nxlog\modules\output\om_kafka.dll, The specified module could not be found.  ; The specified module could not be found.  
2019-06-14 18:28:47 ERROR module 'kafka' is not declared at C:\Program Files\nxlog\conf\nxlog.conf:84

However om_kafka.dll100% persist in folder C:\Program Files\nxlog\modules\output\ I'm trying to reinstall, repair, install on x32 and x64 same as Windows Server 2012R2 and Windows Server 2016

Similar module om_kafka works fine on Centos7

Seems that “out of the box” this module is not working on OS windows , I mean, what am I missing? maybe any additional librdkafka installation required?

    The above error is likely caused by a library missing that om_kafka.dll needs.
    Do you also have the C:\Program Files\nxlog\librdkafka-1.dll ?

    Yep, C:\Program Files\nxlog\librdkafka-1.dll was in place, 1.02MB size

    As per B0ti's answer, please re-download nxlog-4.4.4347.
    There was a packaging error, and it has since been corrected.

The fixed msi packages have been uploaded today, though the version number did not change.
