CSViewer outgoing calls

I want to install CSViewer at a clients server. They tested the software and said that it was doing outgoing calls and that they don't allow software on their servers that do outoing calls. Is it possible to configurate the installation so to turn of these calls?
Thanks in advance!

Hi Aron and welcome to the Community!

CSViewer does 2 requests on startup - check for new versions and fetch news. You can disable both as follows:

In menu "About", open the update checker and select "I'll check for updates myself".

On the start screen, uncheck "Fetch latest news...".

Both settings are saved in the configuration file so you can change them once after installation.
