MSVCP90.DLL is missing

I installed Microsoft Visual Studio 9.0 and created a simple command line C++ project (.EXE file). When I'm trying to execute it an error modal window开发者_运维百科s is saying: "The program can't start because MSVCP90.DLL is missing from your computer".

The file exists on the machine at c:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x86\Microsoft.VC90.CRT\msvcp90.dll.

What am I doing wrong?
