updates not applying even though it finds the new version on server

I'm running into an issue where when I run wyupdate, it doesn't apply the changes in my code. It finds the correct version number, it displays the change notes, but it doesn't actually apply the changes. I have all my files and folders included in the "your program" folder. When I run the .exe from the installer, the correct changes are applied. But when I upload the changes to the server and try to update from a separate machine, the code stays exactly as it was on the previous build. Can you help? I've included wyupdate.exe in the initial installer as well as a client file. Do I need to put a fresh client file in the "update files" for every new build? Or is that first client file that I put in there sufficient?

Best advice, follow this: https://wyday.com/wybuild/help/walkthrough.php

Also, keep your versions in separate folders (don't build updates from a common folder -- wyBuild doesn't remember your old versions you need to keep them separated).

I have just followed that walk through example to a T. I didn't skip any steps and everything worked the way it should have, except I'm still getting the exact same outcome. I have my files stored in two separate folders 1.1, 1.2, I check the source files in those folders and the small change i made between the two of them is definitely there. When i build my installer with 1.1 and install it on a separate machine, and upload 1.2 to my server, the separate machine will see 1.2 is built, go through the update process, but the version that was on the initial installer, 1.1, is still the version that gets launched.
