+{
+    Write-Host $UiStrings.DependenciesFound
+    $DependencyPackages.FullName
+
+
+    # Install dependencies one by one first
+    foreach ($dep in $DependencyPackages.FullName) {
+        echo "Installing dependency: $dep"
+        try {
+            Add-AppxPackage -Path $dep -ForceApplicationShutdown
+            echo "Successfully installed: $dep"
+        } catch {
+            echo "Failed to install dependency: $dep - $($_.Exception.Message)"
+        }

+
+    # Now install the main package
+    echo "Installing main package: $($DeveloperPackagePath.FullName)"
