I recently started getting this error when trying to run a project that uses the WPF Ribbon. It had been working on this machine prior, but for some reason it's not now. The library from here is installed on this machine properly.
The exact exception message:
"Could not load file or assembly 'RibbonControlsLibrary.Aero2, Version=4.0.0.11019, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.":"RibbonControlsLibrary.Aero2, Version=4.0.0.11019, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Current system/project environment: .NET 4, VS 2010 Pro, Win8 Pro
Modifying the project for VS 2012 Express for Desktop and the .NET 4.5 ribbon controls there works fine, though we can't switch to VS 2012 just yet so need to get this fixed for VS 2010.
The project still works fine on the Win7 systems.
