Please don't copy files from other working computers
Can you expand on this statement? I've done it before with no problems. I'm curious why this would pose a problem provided you aren't grabbing files from a Windows 7 machine and trying to replace system files on a Windows XP machine.
This file appears to be part of MS Visual. It comes in several different flavours depending on which version you have, most programs bundle these key runtime files with them as they will use certain functionality contained within the file, because that's all a DLL file actually is - a collection of routines that any program on the machine can call.
If you have a program that uses the file and you replace the .dll file with an older version of a file that doesn't have the routine needed, the program will stop working. Just replacing one file can have knock-on effects and the general recommendation is, if the program came with the file that's needed, rather than pinching a copy from somewhere else, reinstall the program in question and it should replace the file with an appropriate version.
and also please don't download DLL files from so-called "DLL Archive" sites. Neither are guaranteed to solve the problem and the latter is simply asking for trouble.
I never recommended the original poster try that.
I know. I added it for the sake of completeness
