This is regarding an error I get every time I try to Refresh the list in the "AppContainer Loopback Exemption Utility" originally written by Eric Lawrence.
I have just installed Fiddler 4 (v4.6.20172.34691, built 2017-08-15) on Windows 10. Upon clicking the "WinConfig" button on the interface, it runs the utility asking for Elevated rights which I grant. The first time I ever ran it, it threw an "Orphaned Exemption Record Found” exception and continued to do so until I reset them by clicking "Except None" followed by "Save Changes."
However, the attached error has persisted. Text below for search indexing. :)
Warning: Unable to use NetIsoEnumAppContainers to get AppContainer list. Error Code: 0x3. Attempting manual registry crawl; some information will be unavailable.

Sorry for the late reply. We were able to reproduce the problem regarding the "Orphaned Exemption Record Found" warning. We will make further investigation and will try to fix the problem for a future version of Fiddler. Please, update your version of Fiddler regularly.
As a temporary, workaround you could click on the "No" button when the warning appears, in order to stop it from poping-up again, until the next time you start the tool again.

The WinConfig button appears if you are running Fiddler on Windows versions greater or equal than 8. The button is used for launching the EnableLoopback utility tool of Fiddler. This tool is used for exempting AppContainers from loopback restrictions. The AppContainer is a technology which was introduced with the Windows 8 Metro Style apps, hence you don't need the WinConfig button and the EnableLoopback utility on Windows 7 and earlier versions.
