[Trying to Open Computer Management] The Program can't start because MSVCR100.dll is missing from your computer. Try reinstalling the program to fix this problem.

I would install the Microsoft Visual C++ Redistributable dll that is needed for projects built with Visual Studio 2010.

Download the files below depending on your operating system version. I would install all versions as they may be needed for different programs. Check in Programs and Features, do you show that you have installed Microsoft Visual C++ 2005 Redistributable and Microsoft Visual C++ 2008 Redistributable? If not, download from the links here.
