    Changes in 7.3.7 Package Installer process?

    In Umbraco 7.3.7 I'm having a problem where installing Merchello "looks" like it fails when the installer throws a YSOD with the following message:

     An unhandled exception occurred
     System.InvalidOperationException: The task runner has completed.
     at Umbraco.Web.Scheduling.BackgroundTaskRunner`1.Add(T task)
     at Umbraco.Web.Strategies.ServerRegistrationEventHandler.UmbracoModul    eRouteAttempt(Object sender, RoutableAttemptEventArgs e)
     at System.EventHandler`1.Invoke(Object sender, TEventArgs e)
     at Umbraco.Web.UmbracoModule.OnRouteAttempt(RoutableAttemptEventArgs args)
     at Umbraco.Web.UmbracoModule.ProcessRequest(HttpContextBase httpContext)
     at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
     at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

    However, after a page refresh, the package (Merchello) has installed successfully.

    I'm not sure if this is an Umbraco bug or something I need to handle due to a change in the process.

    I did notice the Merchello section does not show up prior to the YSOD so I assume that the routing has to do with OnRouteAttempt has to do with Umbraco recognizing a new TreeController - but not at all sure?

    Did you ever find a fix for this? I'm seeing the exact same issue with my Formulate installer on Umbraco 7.4.1:

    And I just noticed it is also apparently happening with Umbraco Forms:

    And it looks like there may be a fix in Umbraco 7.4.2 (so apparently it's a core bug). Might have to give that a try:
