Re: Unable to install/repair/uninstall AT&T Net Client 8.10
Having looked into this further, it looks like one of the custom actions run by the T6 merge module during removal is failing. This makes it a bit more difficult to address, as the T6 merge module custom actions are not specifically included in the AGNC installation/removal sequence, they are automatically included by Windows Installer. The reason this makes it s bit more difficult is that I was thinking we could just alter one of the properties of the action to allow the install to continue even if that specific action failed. However, since we are not specifically including it, I do not think that will work.
So instead, let's try this. The action that is failing is trying to remove one of the T6 firewall rules from the Windows Firewall, and it is failing because that rule cannot be found. Let's try adding the rule manually, so it ought to be found, then see if the uninstall completes. Can you run the following command from an Admin Command prompt and see if the install then completes?
