Features in wyBuild, wyUpdate, & AutomaticUpdater

When you download wyBuild you get a complete updating solution: wyBuild, wyUpdate, and the AutomaticUpdater. Here are some of the top features in wyBuild, wyUpdate, and the AutomaticUpdater control.

wyBuild Features

Use wyBuild to manage versions of your software, customize wyUpdate with your branding & languages, and build update patches.

Easy to use drag & drop

Just drag your files & folders and drop them into wyBuild.

Adding files to wyBuild

Creates shortcuts to your program files

You can create shortcuts on the Desktop or the Program Files menu by simply right clicking a file in wyBuild and clicking “Create Shortcut”.

Create Tiny Update Patches

Using wyBuild is the easiest way to create software patches. It scans the changes between versions of your product and generates industry standard VCDIFF patches (a.k.a. delta patches) to deliver to your users.

For example, updating the bare minimum installation of Nero Burning ROM from version 8.3.2.1 to version 8.3.6.0 (without using wyBuild's patching algorithm) generated an enormous 53.8 megabyte file.

Using wyBuild’s patching algorithm this update size was reduced to a minuscule 1.4 megabytes; small enough to fit on an old floppy disk!

Execute a full range of scripts (*.bat, *.cmd, *.exe, *.msi)

wyBuild lets you select which files you wish to execute files before & after installation. You can even include files that will be extracted to the temp folder, executed during the update, and deleted after the update has completed.

Modify the Registry

Changing the registry is just as easy as adding files. With wyBuild you can manage which Registry keys are created, edited, and removed upon installation of your update. The same goes with Registry values — giving you the ability to delete, edit, or add values of any type (string, binary, or integer data).
