Hello,

I just updated my Streaming Engine instance to 4.7.3, but I got 2 java.io.FileNotFoundException errors during execution of update script, regarding the files:

WowzaStreamingEngine-Update-4.7.3/linux/…/files/lib-native/linux64/srt.list

WowzaStreamingEngine-Update-4.7.3/linux/…/files/lib-native/linux64/libwms-srt.so

I checked the zipfile, and those 2 files are actually present, but in subfolder of “linux64” called “srt”.

The updater then seems to have wrong paths for the 2 files.

Can anyone confirm?

The updater should be amended?

Or just moving the 2 files up in “linux64” folder and re-executing the update script fixes the issue?
