The Detect application install failures machine setting should be configured correctly. This policy setting configures the Program Compatibility Assistant (PCA) to diagnose failures with application installations. If you enable this policy setting, the PCA is configured to detect failures in the execution of application installers through heuristics. When potential failures are detected, the PCA will provide the user with an option to restart the installer with Microsoft Windows XP compatibility mode. If you disable this policy setting, the PCA is not configured to detect failures in execution of program installers. If you do not configure this policy setting, the PCA will enable this diagnostic scenario by default. Fix: (1) GPO: Computer Configuration\Administrative Templates\System\Troubleshooting and Diagnostics\Application Compatibility Diagnostics\Detect application install failures (2) KEY: HKLM\SOFTWARE\Policies\Microsoft\Windows\WDI\{acfd1ca6-18b6-4ccf-9c07-580cdb6eded4}\ScenarioExecutionEnabled
