duplicate installation with the attached script

   ./cyg-reinstall.sh -A
   sed -e "s/setup-x86/setup-x86_64/" cyg-reinstall-x86.bat >=20
cyg-reinstall-x86_64.bat

run the "cyg-reinstall-x86_64.bat" script in the same directory of
"setup-x86_64.exe"

after you can use your 32bit to copy the /home/<your_user>
and all the content of "/etc" that you have customized.

Marco
