This *was* working... not sure what version it broke in, but had to be pretty recent. Was also broken in 520. Thats the earliest one I have.

My main window is named "mainWindow":

<ribbon:RibbonWindow ... Name="mainWindow" ... />

Here are two buttons in my Application Menu:

<ribbon:Button Id="Save" Command="ApplicationCommands.Save" KeyTipAccessText="S" IsEnabled="{Binding ElementName=mainWindow, Path=IsTemplateSetLoaded}" />

<ribbon:Button Id="SaveAs" Command="ApplicationCommands.SaveAs" KeyTipAccessText="A" IsEnabled="{Binding ElementName=mainWindow, Path=IsTemplateSetLoaded}" />

Here is my property registration:

private static readonly DependencyPropertyKey IsTemplateSetLoadedProperty = DependencyProperty.RegisterReadOnly("IsTemplateSetLoaded",
typeof(bool), typeof(MainWindow), new PropertyMetadata(false));

I have made sure I'm not setting IsTemplateSetLoadedProperty anywhere. So its value is false.

Neither command is disabled in the Application menu. If I hardcode IsEnabled="False", they are disabled. If I give the buttons names and set IsEnabled=false; via code, that works too. Just not the data binding.

I'm using the classic ribbon, but it doesn't work with the scenic layout either.

P.S. I have a few buttons in the ribbon itself that use the same exact binding, and those work fine. So it is specific to the application menu.

Ok, I just noticed when I start my app in the debugger, I get the following:

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=mainWindow'. BindingExpression:Path=IsTemplateSetLoaded; DataItem=null; target element is 'Button' (Name='btnSave'); target property is 'IsEnabled' (type 'Boolean')

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=mainWindow'. BindingExpression:Path=IsTemplateSetLoaded; DataItem=null; target element is 'Button' (Name=''); target property is 'IsEnabled' (type 'Boolean')

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=mainWindow'. BindingExpression:Path=IsTemplateSetLoaded; DataItem=null; target element is 'Button' (Name=''); target property is 'IsEnabled' (type 'Boolean')

These are the 3 buttons in the Application Menu that use the binding.

As indicated above, there are 3 additional buttons in the ribbon itself that use this binding and it works fine.

I also set a breakpoint and the static IsTemplateSetLoadedProperty is getting hit before the 3 exceptions, also, I can call SetValue() before the 3 exceptions as well.
