(Windows) Logger Pro 3 shows "No Device Connected" when I connect my interface. How do I reinstall?

The most common problem with Logger Pro on a Windows computer is caused by an issue with how the drivers were installed. Common cases for this are a recent Windows upgrade, or using a modified installer that fails to install the drivers. (We strongly recommend that you do not modify the the Logger Pro installer TIL 1681: How can I install Logger Pro on several computers? Is there an MSI file or a silent installer?.) To solve this problem, you must uninstall and re-install Logger Pro. You will need to be logged in as an administrator.
