How disable Self-update for client.wyc ?

The client.wyc doesn't self-update. wyUpdate does. Yes, you can disable self-update by hosting wyUpdate on your own servers an never updating it. I don't recommend it.

Okej. But when I open client.wyc it have Self-update site witch address to two server's:http://wyupdate.googlecode.com/files/client.wyshttp://wyday.com/files/wyupdate/update/client.wys

Why these addresses are used?

To self-update wyUpdate.exe (the updater program you include with your app). If you don't want to use our servers you don't have to. See: How to make a custom version of wyUpdate

Okej, thanks for the answer, now I know everything 🙂
