ERROR_INSTALL_RESOLVE_DEPENDENCY_FAILED

ERROR_INSTALL_RESOLVE_DEPENDENCY_FAILED means the deployment service could not validate the package update, required dependency packages, or a package conflict.

The error is often resolved by identifying the missing or incompatible dependency in the deployment log, not by repeatedly reinstalling the main package alone.

What to check

  • Use the Activity ID with Get-AppxLog and identify the dependency package family, architecture, and minimum version that failed validation.
  • Provide framework and dependency packages through Add-AppxPackage -DependencyPath when deploying outside the Microsoft Store.
  • Check for conflicting installed packages, including older builds with the same package family name.
Add-AppxPackage -Path .\MyApp.msix -DependencyPath .\Dependency.msix
