I just installed MSVS2008.
I get the following error:

1>------ Build started: Project: test_project, Configuration: Debug Win32 ------
1>Compiling...
1>hello_world.cpp
1>c:\users\rahman\documents\visual studio 2008\projects\test_project\test_project\hello_world.cpp(1) : fatal error C1083: Cannot open type library file: 'c:\program files (x86)\microsoft visual studio 9.0\vc\include\iostream': Error loading type library/DLL.
1>Build log was saved at "file://c:\Users\****\Documents\Visual Studio 2008\Projects\test_project\test_project\Debug\BuildLog.htm"
1>test_project - 1 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Does anyone know what do do?

[EDIT]

I checked and the file does infact exist.
