Application version number not updated in Windows registry after update process

The version shown in "Windows Control Panel -> Programs and Features" is not refreshed after the update process.

I create a new repository for version 1.1.0 and deploy it in my web server, then I run the already installed 1.0.0 version of my app and I get a pop-up saying there is a new version (1.1.0) online available. I accept and update the app, I go to "Windows Control Panel -> Programs and Features" and the old version 1.0.0 is still there.

[Config.xml for version 1.0.0]
