The program can’t start because MSVCR100.dll is missing

Hello,
I have this error in my Windows 7 (x32) and I copied the missing DLL manually, but is not working. Recently I experienced a few more errors with missing DLL. Can anyone help me to fix this one? Why I have these errors with missing DLL?
Thank you!
