[Boost-users] Hello Everyone

I have a problem with installing boost. I downloaded the installer 1.40 for VC 2008 and followed all the instructions in the manual but I'm getting the error 1>LINK : fatal error LNK1104: cannot open file 'libboost_thread-vc90-mt-gd-1_40.lib'. This is from the header #include in my code. Does anyone know what I can possible do to resolve this? Thanks
