What version of the game are you trying to install, retail disk, Steam or other ?
"now "mscvp100.dll is missing" "
It probably was before, but downloading the .dll was not the best way to fix the issue.
Both because it is a bandage solution and potential source of a virus.
It would be better to install, or reinstall C++ 2010 as suggested by ZigZag -

The game very likely also has an appropriate C++ installer in the games install folder.
There is commonly a sub-folder with the term Redist in the title, which has things such as
DirectX and C++ installers in it.
This folder could also be in one of the other sub-folders, such as Binaries.
Some games even have the installer - vcredist+x86.exe - in the main directory.
