VC ++ express, how do I fix this error?

I have experience programming in C#, but I'm taking a C++ class this semester, and I'm writing my second project, but I keep getting this error when I try to build a debug configuration of my program.

My build log is below, any ideas on what's going on? I'm at a loss.

Thanks everyone!

Microsoft blames antivirus for a similar case.

You should look at the buildlog.htm file that is given in the build output. It will give you more (useful) information about what has happened.

try setting your AV to ignore your project directories instead of VC++ directory.

Project : error PRJ0002 : Error result 31 returned from 'C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\mt.exe'.

Faced the same issue Cleaning the rebuilding solved it.

I turned off the Microsoft Security Essentials and the problem is gone. Strange that it only happened for the debug configuration.
