I was configuring iLO access for several servers and in one instance was rewarded with an error message.
The program can't start because MSVCR100_CLR0400.dll is missing from your computer. Try reinstalling the program to fix this problem.
I reinstalled but the error remained. For grins I decided to reinstall the .Net 4.0 and from Microsoft I downloaded the installer. It gave an option to repair it or remove it. I chose to repair it and it solved the problem.
