Missing msvcp71.dll error

Usually run time library files have to be in the same directory as the programs that requires them, in this case maplestory.exe. However, I see no such files in my MS directory, though several versions of these files are all over my computer.
What makes you think MS needs these?

Its the GAME that gives me this error...
And its on other forums and places i learned that i had to put the .dll in win32.
yes, I do find it odd that maplestory needs it, but quite a few programmes do as well.
Apperently its something you get in framework idk.
But yeah... the problem persists...
So I'm wondering if i have to re-install the game or do other things. Or if theres other .dll's i need to download.
