Application Launch, Close, Update, and Install Failures for A+
Short answer
Application lifecycle problems occur at discrete points: install (adding the app), launch (starting the app), runtime (crash/close), and update (patching or replacing app files). Technician checks should be targeted to the failure point: for install, verify storage and app-store credentials; for launch, check permissions, background services, and app data corruption; for crashes, check for known bugs, clear app cache, or reinstall; for update failures, verify OS compatibility, storage and network.
Why it appears on the exam
- Given a short scenario, classify whether the issue is install, launch, crash, or update failure. - Provide the top two first checks for an app that fails to launch but shows no error. - Identify when to escalate (logs, vendor bug reports) vs. user-level remediation (reinstall, clear cache).
Key concepts
Concept 1
Required terms
app launch failure: Application does not start or hangs at startup. app crash (close): Application unexpectedly terminates during use or immediately after starting. app update failure: App update process fails to complete or leaves the app in an inconsistent state. app install failure: New app fails to install from the app store or sideloading process fails.
Example
Install failure: Installer error 'insufficient storage' when trying to add a new social-media app. First checks: storage free space, app-store account, and compatible OS version.
Concept 2
How Application Launch, Close, Update, and Install Failures works
Application lifecycle problems occur at discrete points: install (adding the app), launch (starting the app), runtime (crash/close), and update (patching or replacing app files). Technician checks should be targeted to the failure point: for install, verify storage and app-store credentials; for launch, check permissions, background services, and app data corruption; for crashes, check for known bugs, clear app cache, or reinstall; for update failures, verify OS compatibility, storage and network.
Example
Launch failure: App shows splash screen then returns to home. First checks: force-stop and relaunch, check permissions, clear cache/data, reinstall if persistent.
Concept 3
Common confusion
Learners often collapse all app problems into 'the app is broken.' Distinguish where in the lifecycle the symptom occurs; many fixes are different (e.g., reinstall for corruption, storage free-up for install, permission change for launch).
Example
Crash: App closes when opening a specific feature. First checks: check for updates, inspect crash dialog, review recently installed apps or OS updates.
Concept 4
Core 2 (220-1202) question cues
Given a short scenario, classify whether the issue is install, launch, crash, or update failure; Provide the top two first checks for an app that fails to launch but shows no error; Identify when to escalate (logs, vendor bug reports) vs. user-level remediation (reinstall, clear cache).
Example
Update failure: App update stalls with store error. First checks: verify network, available storage, and restart device; if store credentials are the issue, sign out/in.
Sample questions

Q1.A technician is troubleshooting this situation: Install failure: Installer error 'insufficient storage' when trying to add a new social-media app. First checks: storage free space, app-store account, and compatible OS version. What should they identify?
Q2.For this A+ objective, the scenario says: Launch failure: App shows splash screen then returns to home. First checks: force-stop and relaunch, check permissions, clear cache/data, reinstall if persistent. What is the best match?
Q3.An A+ support scenario describes this situation: Crash: App closes when opening a specific feature. First checks: check for updates, inspect crash dialog, review recently installed apps or OS updates. Which answer fits best?
