Hey Mattias,
I have been using your fantastic wyBuild for quite a while now and I am absolutely loving it! It helps me focus on the actual application instead of tinkering with annoying update problems all the time!
Thanks, that means a lot.
Have you considered creating a similar application for installing applications?
Yes, it's coming in wyBuild 2.8. (We're working heavily on this feature, among others). There's no hard release date, yet, though. So unfortunately you'll still have to suffer through the other crummy installer makers for now.
