Error When Launching Application

Hi, I added the AutomaticUpdater Control to the WinForm Application, but I am getting the following error "System.IO.FileLoadException: Could not load file or assembly 'AutomaticUpdater, Version=2.6.18.4, Culture=neutral, PublicKeyToken=d2050be9b2e72e40' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference."

What did I do wrong?

Sorry for the newb question.

Also, just to confirm, I put a copy of the AutomaticUpdater.dll and the AutomaticUpdater.dll.xml inside the application's working directory. But we are still getting the error: https://imgur.com/a/N6hw1sF

You're not including the AutomaticUpdater.dll in the same directory as your exe and/or you're link with the .NET 2.0 in a .NET 4.x app (or vice versa).

Beyond that, the default debugging methods apply:

1. Does the executable run in the debugging environment? If not, fix it there first.2. Are you using some sort of "wrapper" program? If so, stop using it.

That fixed it. Thank You.
