There are a couple tools that you can use to clean up an orphaned installation. The attached zip file contains both tools.
1. msicleaner.exe - run the exe - If it lists the QLM installation, click Remove to remove it. If it does not list the QLM installation or the remove fails, try the other tool.
2. msicuu2.exe - first install this tool - the actual tool is called Windows Installer Cleanup. After you install it, run the "Windows Installer Clean up" app. You will see a dialog like the one below. Locate Quick License Manage and click Remove.
If the above fails, you will need to resort to directly editing the registry to cleanup the installation.
Note: We are not the author of these tools and take no responsibility in any issue that may arise in using them.
