PORestartManager fails to restart application during update
text
Body
copied!<p>I'm using c#, .net 4, WIX 3.5, Windows Vista. I have made my application compatible with RestartManager by p/invoking the RegisterApplicationRestart method and by handling the WM_QUERYENDSESSION and WM_ENDSESSION window messages (I return <code>new IntPtr(1);</code>).</p> <p>If I try to update my application manually, then everything works as it should:</p> <ol> <li>Launch application;</li> <li>Launch msi file containing new app version;</li> <li>During the installation/update, I'm prompted to close the running application;</li> <li>Upon continuing the running app is closed, install completes, and the app is restarted;</li> </ol> <p>If I try to update my application from the application itself, then I run into problems:</p> <p>1) Launch application;<br> 2) Download the new msi file;<br> 3) Launch msi file with: </p> <pre><code> using (System.Diagnostics.Process p = new System.Diagnostics.Process()) { p.StartInfo.UseShellExecute = false; p.StartInfo.FileName = "msiexec"; p.StartInfo.Arguments = "/i \"" + downloadPath + "\" /passive"; p.StartInfo.UserName = "Administrator"; p.StartInfo.Password = securePassword; p.Start(); } </code></pre> <p>4) Because I'm using passive mode, the application is closed automatically;<br> 5) After the installation, my application is not restarted and under Event Viewer I have an<br> Event 10007 - <em>Application or service 'MyApp' could not be restarted</em>.</p> <p>I have tried:</p> <ol> <li>Not to use passive mode for msiexec;</li> <li>Launch msiexec via cmd.exe (cmd.exe /C "msiexec /i ....") - in the hopes that launching msiexec from another process would solve the problem;</li> <li>Wait for 60+ seconds before launching the msi update (shouldn't be relevant in my scenario, but MSDN documentation has something about it...)</li> </ol> <p>But none of the above has worked (always the same result).</p> <p>Having to launch the setup with elevated permissions might have something to do with the issue, because during the manual update I get a warning in the Event Viewer - <em>Application MyApp (pid 3220) cannot be restarted - Application SID does not match Conductor SID</em>.<br> Despite this, restarting the app still works. Googleing the warning yields no good/specific results, only that this warning is probably caused by running the msi in an elevated prompt.</p> <p><strong>How do I fix (or workaround) this issue, so that I can update my application from the application itself and restart my application afterwards?</strong></p> <p><strong>Edit - extra testing:</strong></p> <ol> <li>There doesn't seem to be a need to respond to WM_QUERYENDSESSION and WM_ENDSESSION messages, because application restart during a manual upgrade works without them, so we can rule them out;</li> <li>If I don't provide administrator credentials to the application initiated upgrade and instead I type them in during the upgrade, then app restarting works;</li> <li>If I run an elevated command prompt and initiate an application upgrade from there (manually), then app restarting still works;</li> <li>In order for application upgrade to work at all under Standard user accounts (so far I tested under an Administrator account with UAC), then I also have to set <code>p.StartInfo.LoadUserProfile = true;</code>. Otherwise nothing happens. (application restart still doesn't work though);</li> <li>I tried all other process StartInfo parameters that I could set - WorkingDirectory, Redirect, Verb<br> (= "runas") - no change in results;</li> <li>I installed Vista SP2 onto the virtual machine that I have been testing on (so far ran SP1), but no change;</li> <li>I performed an "automatic" application upgrade with verbose logging. In the end there was an error message - <strong>RESTART MANAGER: Failed while restarting applications. Error: 352</strong>. That error code is very generic (<a href="http://msdn.microsoft.com/cs-cz/library/aa373665" rel="noreferrer">http://msdn.microsoft.com/cs-cz/library/aa373665</a>), inorder to get more detailed info I would have to write my own installer that would call <em>RmGetList</em> after the error, then I might get more details (this though is something I'm not willing to do);</li> </ol> <p><strong>Edit 2 - msi log file:</strong><br> <a href="http://mommi.planet.ee/muu/log.txt" rel="noreferrer">http://mommi.planet.ee/muu/log.txt</a></p>
