I want to experiment with installing apps with bundles on Windows 7 with ZCM 11.2. I create the bundle and run it and it installs. Now I want to test another condition so I uninstall the bundle (using Uninstall from Control Panel | Programs and Features) and then try to run the bundle again - it won't install now. I make a change to the bundle in ZCM, then publish a new version and then sometimes it will install and sometimes not.

What is the correct way to uninstall a bundle so you can try to install it again? What am I missing?
