Trying to change wyUpdate error message

I have built my own copy of wyUpdate.exe and I thought I had changed all instances of "wyUpdate" to my application name. I occasionally get the error "wyUpdate ended before the current update step could be completed" with wyUpdate still in it. I tried searching the solution/project for it and I cannot find the string "ended before".

Where is this error message coming from? Can I change it?

This is an AutomaticUpdater error. This is likely caused by a crash in your custom wyUpdate build. Attach a debugger to your version of wyUpdate to see why it's exiting prematurely.

If this message is coming from AutomaticUpdater, that means I cannot change it, correct?

All I did in my version of wyUpdate was to change "wyUpdate" to my application name - I made no other code changes. This is also happening (so far) only when I am debugging my application. I will try to trap the error.

You can modify the AutomaticUpdater source code if you want.
