OK I've updated and got some more help, but I'm still stuck with

os.environ BOOST_ROOT boost-root = 
Jamfile.v2:30: in modules.load
*** argument error
* rule path-constant ( name : value + )
* called with: ( local-boost-root :  )
* missing argument value
I:/boost_1_44_0/tools/build/v2/build\project.jam:1002:see definition of rule
'path-constant' being called
I:/boost_1_44_0/tools/build/v2/build\project.jam:310: in load-jamfile
I:/boost_1_44_0/tools/build/v2/build\project.jam:62: in load
I:/boost_1_44_0/tools/build/v2/build\project.jam:168: in project.find
I:/boost_1_44_0/tools/build/v2\build-system.jam:569: in load
I:\boost_1_44_0\tools\build\v2/kernel\modules.jam:283: in import
I:\boost_1_44_0\tools\build\v2\kernel\bootstrap.jam:142: in boost-build
I:\boost-sandbox\boost-build.jam:62: in module scope

and tried adding and changing the environment variables so they are now thus

C:\Users\Paul>set boost
BOOST=I:/boost_1_44_0/
boost_build=I:\boost_1_44_0\tools\build\v2\build   << or should this be
I:\boost_1_44_0\tools\build??
boost_build_path=i:/boost_1_44_0/tools/build/v2
boost_patches=i:\boost-patches
boost_root=i:/boost_1_44_0/
boost_sandbox=i:\boost-sandbox
boost_trunk=i:\boost-trunk

It seems that boost_root environment variable is not being seen correctly?
So I'm doing something wrong still.

Thanks

Paul
