How can I make selfupdate.wys file?
We go into this in the "How to make a custom version of wyUpdate" article
Why should I do this?
Because no software is perfect. You want to update your software and you should want to update wyUpdate. We fix bugs and add features.
The question is - can i download old version of wyUpdate application (wybuild-setup.exe)?
No. Old versions have bugs (more bugs than new versions).
Is there a way how to disable auto update of wyUpdate?
No. Well, you could remove the ability from wyUpdate, but that's a bad idea.
