My ClickOnce application is currently on version 2.0.0.12. I updated the application, changed the published and assembly version # to 2.0.0.13. When I start the application on a client desktop it checks for an update but does not recognize an update is available and runs as normal.

I launch fidler and watched the request and the manifest it is pulling back still has the 2.0.0.12 version reference. 

On the server I deleted the 2.0.0.12 version all together, turned off caching on the server and uninstalled the app from the desktop.

When I launch the installer it fails downloading files because it can't find the 2.0.0.12 version folder. I updated the Application.htm, Setup.exe and .application files on the server and they reflect the correct 2.0.0.13 version.

My question is: Where the heck is the ClickOnce app getting the reference to the previous version from?

Here is the error log:
