Current version number

You have to embed it in your app and read it from there. The AutomaticUpdater only shows new versions.

I'm sorry, how might I do that?

Like this:

FileVersionInfo.GetVersionInfo(SelfLocation).FileVersion

I suspect that 'SelfLocation" is where the 'client.wyc' lives. So I do this:label1.Text += System.Diagnostics.FileVersionInfo.GetVersionInfo(Application.StartupPath + "\\client.wyc").FileVersion;However, that does not show anything.

No, selflocation is where the exe is.

FileVersionInfo.GetVersionInfo("C:\\Full\\Path\\To\\Your.exe").FileVersion

That shows '1.0.0.0'. I'm looking for the 1.5 that the client.wyc file shows.

I apologize, I must be confusing it.

You have 2 options: either parse the client.wyc file (open the wyUpdate source code to see how to do it) or embed your app's version in your app. If you're making C# app then edit the Assembly.cs file. If it's a VB.nET app then there's some dialog somewhere in the project properties (I can't remember where -- Google will tell you).
