The complete warning message is "This method loads themes for all existing components and will generate an exception if one of the components is not installed. Use LoadEmbeddedTheme(EmbeddedTheme theme, Product product) method instead. For the list of existing components see Elegant.Ui.Products enum". Starting from v.3.1, visual themes are loaded in a completely different way. Both Elegant Ribbon and Elegant Common Controls have their own sets of visual themes, which are stored in separate assemblies. Because of that, you should load the needed themes separately for each product by using the following method:

[C#]

LoadEmbeddedTheme(EmbeddedTheme theme, Product product);

[VB.NET]

LoadEmbeddedTheme(EmbeddedTheme theme, Product product)

In the ..\Program Files\FOSS Software Inc\Elegant Ribbon\Bin folder, you can find several assembly files with visual themes. Each file corresponds to a particular visual theme (for example, System) for a particular product (for example, Elegant Ribbon). You should make that all assemblies with the themes you are using in your application are available on client machines. So, if your ribbon-based application uses only the System theme, these are Elegant.Ui.Ribbon.Theme.System.dll (for the ribbon) and Elegant.Ui.Common.Theme.System.dll (for common controls). We would recommend to put these assemblies into GAC.

The System theme makes your application having a visual style provided by the operating system on which it is running. The supported visual styles include those available on Windows OSes starting from Windows 2000 including Windows Vista. Please note that custom classic theme colorizations are also supported.
