To use the SDK compiler, you need to do a few manual steps first.

After starting a command window, you need to run a batch file to configure your environment. Choose the appropriate option from C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\vcvars64.bat or C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\vcvars32.bat Then set two environment variables: set MSSdk=1 set DISTUTILSUSESDK=1 After these steps, the standard python setup.py install should work. This may be fine for building extensions, but it appears that more instructions are needed for a novice to build python itself. I'm not even sure that these variables are necessary - certainly without the compilers installed setup.py looks in the right place for them. I'll try this as well.

Setting MSSdk shouldn't be necessary, as vcvars should already have set it (unless that changed in recent SDKs). Setting DISTUTILS_USE_SDK is necessary as a protection to avoid unintionally picking up the wrong build tools.

As for distutils finding them automatically: this only works for finding VS installations. It is (AFAICT) not possible to automatically locate SDK installations (other than by exhaustive search of the disk).

As for the documentation, I'd be happy to provide an update for this section once I've checked out that everything works.

I think it should explain to to invoke msbuild, in addition to explaining how to plug old compilers into new IDEs.
