Error 28 means you might have a network adapter that is currently disabled.
Even if that adapter is not actively used, it should still be enabled temporarily just to activate the product.
Here are the steps:
Once it works, you can disable the network adapter again.
Option 2: Update the Network Adapter
In Device Manager, locate the ‘Network adapters’ and double-click on it to view your adapters.
If any of them appear disabled or have an icon next to the name, here is how you can enable it. Please do that for all network adapters.
If the above did not help, you might need to update your drivers.
In the Device Manager, right-click on the ‘Ethernet’ network adapter, and select ‘Update driver’ from the context menu.
In the ‘Update Drivers’ window, you will now find two options, either to let Windows automatically search for the best available drivers on the system or locate and install them manually. It’s recommended that you select the first option and let Windows take care of the installation.
Please repeat that for all network adapters on your computer.
In some cases, it might be necessary to manually install the drivers. For most users, this link should work:
