Please check if you have any network adapter that has a name similar to the tunnel name you are trying to use (Control Panel\Network and Internet\Network Connections). WireGuard needs to have a network adapter with the name that corresponds to the tunnel name. In your case, it fails naming it.
Maybe you named your Ethernet/Wifi adapter as "MyCompany", and then created a WireGuard tunnel with the same name "MyCompany". Maybe you have a WiFi SSID named "MyCompany". Try picking different name for your WireGuard tunnel. Other than WireGuard tunnel and adapter names must be aligned internal limitation, the name of the tunnel doesn't play any significant role. You can select a different name (e.g. "MyCompanyWG", "wg0", etc.) and try again.

When I create a tunnel and try to connect, I get: Unable to create Wintun interface: Error creating interface: Unable to set name of Wintun interface: NciSetConnectionName failed: The requested operation was made in the context of a transaction that is no longer active. I have uninstalled and reinstalled from the command prompt as the administrator. I have validated the tunnel works with the configured parameters on a Mac. Any suggestions? Mark Nichols Discrimination, oppression, and injustice are challenges to be overcome, tools to sharpen our determination, and reflections on the poor character of the oppressor. Lack of opportunity is a calling to create something new and better. If we choose to see circumstances as something to overcome on our way to success instead of allowing them to define us as a victim, we retain the power to pursue our highest destiny.
