I only have .NET 1.1 and 2.0 and Visual Studio 2005 (8) installed. Why should I forget about it? Is Python compiled with much older compilers and thus unable to work together in a nice way or?

The standard Python binary uses the MSVC 7.1 CRT (msvcr71.dll). Visual Studio 2005 will not compile code which uses that CRT, so Python extensions built with that compiler are not compatible with Python built to use msvcr71.dll.

The only compilers supported for building extensions compatible with the standard Python binary are gcc (mingw) and VS 2003 (MSVC 7.1) (including the free MS Toolkit compiler 2003 if you have it, but sadly MS have withdrawn it from distribution) - precisely because they have options to link with msvcr71.dll.

Paul.
