The above error relates to the Microsoft Visual C++ Redistributables. Uninstall each of the following through Start Menu -> Control Panel -> Uninstall a program. Then re-install them from the links given below:
Visual C++ 2005 Redistributable (x86)
Visual C++ 2005 Redistributable (x64)
Visual C++ 2008 Redistributable (x86)
Visual C++ 2008 Redistributable (x64)
Visual C++ 2010 Redistributable (x86)
Visual C++ 2010 Redistributable (x64)
You need both the 64-bit and 32-bit (x86) versions. Then, you need to install the updates for all of them through Windows Updates.
