     Currently, the extension doesn't include a selection for the latest runtime versions. If you want to set the runtime version higher than 1.2, open *deployment.debug.template.json* deployment manifest file. Change the runtime version for the system runtime module images *edgeAgent* and *edgeHub*. For example, if you want to use the IoT Edge runtime version 1.4, change the following lines in the deployment manifest file:
 
     ```json
-    ...
     "systemModules": {
        "edgeAgent": {
-       ...
-          "image": "mcr.microsoft.com/azureiotedge-agent:1.4",
-       ...
+        //...
+          "image": "mcr.microsoft.com/azureiotedge-agent:1.4"
+        //...
        "edgeHub": {
-       ...

           "image": "mcr.microsoft.com/azureiotedge-hub:1.4",
-       ...
+       //...
     ```
 
 1. If you changed the version, regenerate your deployment manifest by right-clicking the name of your project and select **Generate deployment for IoT Edge**. This generates a deployment manifest based on your deployment template and appears in the **config** folder of your Visual Studio project.

 1. Replace the *image* property value with the module image name you pushed to the registry. For example, if you pushed an image tagged `myacr.azurecr.io/iotedgemodule1:0.0.1-amd64` for custom module *IotEdgeModule1*, replace the image property value with the tag value.
