Hi,

I have an app which has been signed with a developer profile. The app is already installed on the device. Then I tried to launch Appium inspector and I get error as “Failed to start an Appium session, err was: Error: Installing”

Appium Version:1.4.13  
OS : OS X 10.11.1  
iOS : 9.1

In my device Settings-\>General-\>Enable UI Automation is set to YES.

**My Questions:**

1. Why I am seeing “App is not installed” in log when the app is already installed in device?
2. Xcode instruments automation tool is able to lauch the app which means the app has right development profile.Or Am I missing something?

**Full Appium Log:**  
Launching Appium with command: ‘/Applications/Appium.app/Contents/Resources/node/bin/node’ lib/server/main.js --address “127.0.0.1” --port “4725” --callback-address “127.0.0.1” --callback-port “4723” --command-timeout “7200” --debug-log-spacing --platform-version “9.1” --platform-name “iOS” --app “tv.accedo.tve.demo.ios.appium” --udid “93b14e455cd2de136ed17f0ec59ba88e85a923be” --full-reset --show-ios-log --show-ios-log --device-name “iPhone 6 Plus” --native-instruments-lib --orientation “Portrait”

I would suspect that the bundle id was changed at some point. Here are some good instructions for getting the bundle id:
