Check for updates without updating

I am adding the automatic updater to a wpf about window so that the user can see if their copy of our program is up to date. However, when I run the update it starts to download the update and actually install it. How would I go about having the automatic updater just check for an update without updating. I saw where it is possible to have the wyUpdate run and return without trying to update, however I cannot get the process to return and run a storyboard afterward. I you would code samples, just let me know.

TL;DR: I cannot get the wyUpdate.exe to work as a separate process from a WPF window and throw and event that causes the wpf window to animate.
