Below are the requirements for wyBuild, wyUpdate, and the AutomaticUpdater control.

Requirements for wyBuild

wyBuild manages versions of your software and creates patches from one version to the next.

The .NET Framework 2.0 is the only requirement for wyBuild. If you don't have it, it's automatically downloaded and installed when you run the installer.

Requirements for wyUpdate

wyUpdate is the open source (and royalty free) updater program you include with your software. The requirements for wyUpdate are either the .NET Framework 2.0 or the .NET Framework 4.0. You can choose which one by going to "File -> Properties -> wyUpdate" inside wyBuild:

wyUpdate for .NET 2.0 or 4.0

It's installed by default on Windows Vista and above (Windows 7, 2008, Windows 8, etc.) and over 96% of Windows XP computer have it installed. So if you have any doubt which one to choose, then choose the .NET 2.0 version.

Requirements for the AutomaticUpdater control

AutomaticUpdater works with .NET applications built for any of the following versions of the .NET Framework:

wyBuild, wyUpdate, and the AutomaticUpdater control are fully compatible with Windows 2000 through Windows 10 (both 32-bit & 64-bit versions of Windows):
