The wyUpdate executable was not found:

I received this error when my app starts: The wyUpdate executable was not found: (directory path to main executable).E.g. The wyUpdate executable was not found: "C:\Program Files\My Company\My App Dir"

I noticed that the file name is not in the path, its just the directory path.

I tried manually creating the path during initialization of the form, including the wyUpdate.exe file name. However the message is always the directory path to main executable and not the path I populated the AutomaticUpdater1.wyUpdateLocation property.

I carefully stepped through my code to confirm it is populating the wyUpdateLocation property during the forms initialization but at some point the property is overwritten to be the main executable path. I have checked my code and cannot see anywhere where I touch the wyUpdateLocation property besides the form initialization.

Have you heard of this before?

A lot more information is needed. Starting with the full exception. And all options you're passing to your application. Also, are you using full paths or just the filename? Use full paths.
