Having trouble with .dll errors?

ok, i got a copy of Bit.Trip Beat for PC from a friend, but when i installed it, I guess the installer was wonky, because it came missing some .dll files. I found the files, but now there's a new problem, it's saying "the procedure entry point_invalid_parameter_noinfo_noreturn could not be located in the dynamic link library MSVCR100.dll." and I have no idea what it means. I've tried moving the dll files, tried finding out what to do, and I've got nothing. help please?
