Cannot install and configure iotedge runtime (Windows 10)

Question

Hi,
I have a problem with installation iot edge runtime on Windows 10.
On the computer was installed older releases of Windows Admin Center,
I tried to install IoT Edge runtime (with older IoT Edge exptension) but got error (unfortunately I didn't keep this message) during installation.
Then I found that MS release new release of Windows Admin Center, so I uninstalled not working edge runtime from Windows Admin Center, and updated Windows Admin Center to last version (also I updated all installed extensions).

Now I can install edge runtime but on the last stage "Connect" (I specified manual method with connection string) I got error "Error: Aborting, iotedge was previously provisioned (headless mode)!" . When I open Edge runtime from Windows Admin Center I see in the log:

* iotedge.service - Azure IoT Edge daemon

I tried to provision edge device with Powershell script Provision-EflowVm but without success - it runs forever (wait for about 2 hours and then terminated it)

Can you suggest how to reinstall Edge Runtime from the scratch?

Thanks,
Oleg

Answer 1

@Oleg Glad to hear that you are unblocked. I believe you are following this documentation.

You can use the dashboard extension in Windows Admin Center to uninstall Azure IoT Edge for Linux on Windows and then install again. Below are the steps for uninstalling IoT Edge.

• Connect to the IoT Edge device in Windows Admin Center. The Azure dashboard tool extension loads.
• Select Uninstall. After Azure IoT Edge is removed, Windows Admin Center removes the Azure IoT Edge device connection entry from the Start page.

Another way to remove Azure IoT Edge from your Windows system is to select Start > Settings > Apps > Azure IoT Edge LTS > Uninstall on your IoT Edge device. This method removes Azure IoT Edge from your IoT Edge device, but leaves the connection behind in Windows Admin Center. To complete the removal, uninstall Windows Admin Center from the Settings menu as well.
