After reading the start guide i tryied to install the regex from the command prompt of Visual C++ Express:
D:\programmi\boost\boost_1_35_0\libs\regex\build>nmake -fvc8.mak
now i have a new vc80 directory
an then:
D:\programmi\boost\boost_1_35_0\libs\regex\build>nmake -fvc8.mak install
with this error:

Building Boost.Regex without ICU / Unicode support:
Hint: set ICU_PATH on the nmake command line to point
to your ICU installation if you have one.
        copy vc80\libboost_regex-vc80-mt-s-1_35.lib "..\..\VC\lib"
Impossibile trovare il percorso specificato.
        0 file copiati.
NMAKE : fatal error U1077: 'copy' : return code '0x1'
Stop.

The traduction is: impossible finding the specifiyed directory, 0 files copyed.

Have i made a mistake?
Thanks and regards!
