I'm testing a second pc with an outside view - but the weather isn't synced - actually nothing is sent to the client about weather?

 

It says "live view"-weather networked in both client and server of opusfsx 

 

any clue?

You must step through the Getting Started guide for Networked PCs. Your client most likely cannot access the weather theme file on the server. It has to transfer this file and copy it to your FSX weather theme folder on your client system. Hence you must set all the sharing, security and permissions on both systems to ensure the correct file access and writing privileges. You must also set up your network as described in the manual to allow access to your weather theme file on your server system by the client system.
