Starting Cubase or Nuendo especially on Windows 8 may lead to the error message
"LoadLibrary failed with error 126: The specified module could not be found"
This error message appears when Cubase and Nuendo is initialising the video engine.
This error is related to the generic graphics card driver provided with the Windows installation and happens mainly with AMD/ATI based solutions.
Please download and install the latest available version of the graphics card driver for your hardware at www.amd.com
Another option can be the installation of the "Visual C++ Redistributable Packages for Visual Studio 2013" which can be downloaded here.
