Build error in windows 7

[register]

When I try to build from source in Windows 7, x64, visual studio 2010 full,
perl-5.14.1 I get the following error:

        link -subsystem:console -out:..\generate_uudmap.exe
@C:\Users\lucar\AppD
ata\Local\Temp\nmD6A3.tmp
..\generate_uudmap.obj : fatal error LNK1112: module machine type 'X86'
conflict
s with target machine type 'x64'
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio
10.0
\VC\BIN\link.EXE"' : return code '0x458'


I didn't find any solution looking on the internet. Some suggestions?

Thanks,
