Windows Clients Tunneling in Adobe Connect Meetings
The new Adobe Connect Meeting Application version 2019.3.3 is live for Windows: Find the standalone, lightning and MSI downloads here: https://helpx.adobe.com/adobe-connect/connect-downloads-updates.html
Some legacy Windows 7 clients (and others with later client Windows OS versions) may begin tunneling into Meetings or experince other connectivity issues when using this new application. To solve this and allow a direct RTMP(S) connection to Connect Meetings for these legacy clients, add the following line to the mms.cfg file in either: /Windows/system32/Macromed/Flash (32-bit Windows) or /Windows/SysWOW64/Macromed/Flash (64-bit Windows).
If the affected Windows 7 client does not have an mms.cfg file, you may create one or download one from here: http://platinum.adobeconnect.com/mms/default/mms.zip
Extract the mms.cfg file and place a copy in: /Windows/system32/Macromed/Flash (32-bit Windows) or /Windows/SysWOW64/Macromed/Flash (64-bit Windows).
Simply add this line to the existing mms.cfg on win 7 clients that are tunneling (where no other clients tunnel). Edit it or create it (it is a simple file to create) or download it and place into the directory listed above.
