1. Install Qt Creator.
   In Windows' Control Panel there will be an entry for uninstalling Qt Creator.
2. Install Qt Creator to another directory.
   In Windows' Control Panel there will still be only one entry for uninstalling Qt Creator. When this is started, it will remove the second installation of Creator and disappear. Then, the only way of removing the first installation is to pick QtCreatorUninst.exe from the file system.

To avoid this, the installer should either:

• Create another entry in Windows' Control Panel (don't know if this is possible)
• Create a shortcut like "Uninstall Qt Creator" in the Start Menu.
