title: install UWP app by App Installer from web error, dependency package missing
body: <p>I have an UWP app and try to install it from web via App Installer. According to the <a href="https://docs.microsoft.com/en-us/windows/uwp/packaging/installing-uwp-apps-web" rel="noreferrer">docs</a> I can put <em>.appx/</em>.appxbundle/*.appinstaller and I have appxbundle one which is generated by VS 2017. </p>
  
  <p>When I put appxbundle (also all generated folder/files like Add-AppDev{ackage.resources and Dependencies) on my host server and try to download/install it, the App Installer is called and shows my app manifest info correctly. </p>
  
  <p>However the installation fails on my client machine and complains "<strong>App Installer failed to install package dependencies. Ask the developer for Microsoft.NET.CoreRuntime.1.1 package</strong>". It did install alright on my dev machine for I'm guessing I have all the sdks installed already.</p>
  
  <p>I tried putting dependency info in my appinstaller file like below but still no good.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;AppInstaller 
      xmlns="http://schemas.microsoft.com/appx/appinstaller/2017" 
      Version="1.0.0.0" 
      Uri="http://myhost.com/myapp.appinstaller" &gt; 
      &lt;MainBundle 
          Name="MyApp"
          Publisher="CN=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
          Version="0.0.1"
          Uri="http://myhost.com/myApp.appxbundle" /&gt;
  &lt;Dependencies&gt;
      &lt;Package Name="Microsoft.NET.CoreRuntime.1.1" Publisher="CN=Microsoft Corporation, O=Microsoft Corporation, L=Redmond, S=Washington, C=US" Version="1.1.25305.1" ProcessorArchitecture="x86" Uri="http://myhost.com/Dependencies/x86/Microsoft.NET.CoreRuntime.1.1.appx" /&gt;
      &lt;Package Name="Microsoft.NET.CoreRuntime.1.1" Publisher="CN=Microsoft Corporation, O=Microsoft Corporation, L=Redmond, S=Washington, C=US" Version="1.1.25305.1" ProcessorArchitecture="x64" Uri="http://myhost.com/Dependencies/x64/Microsoft.NET.CoreRuntime.1.1.appx" /&gt;
  &lt;/Dependencies&gt;
  &lt;/AppInstaller&gt;
  </code></pre>
  
  <p>Can someone tell me what go wrong?</p>
  
  <p>Thanks!</p>
