LNK1104: cannot open file 'msvcprt.lib'
===

I'm using Visual Studio 2010 Express on a Window 7 machine. Two days ago, my project compiled just fine, but all the sudden it get this linker failure:

> LNK1104: cannot open file 'msvcprt.lib'

In between, I installed MS Office 2010 on that machine and Windows installed a bunch of updates, that's all. Seems like Windows / VS "lost" a file!? (how can that even happen?) What can I do about this?
