The Issue
In some instances, Windows will display a "No Internet" indicator regardless of network connectivity, IP configuration, and ability to browse the web. Although in these cases the networking stack is [mostly] functioning properly, this will sometimes interfere with tasks such as software installations. This issue typically relates to the Windows connectivity checks/activity probes, and can be resolved by modifying the respective registry keys.
