Hi, Werner. I've been running the release candidate of Windows 7 and haven't encountered that issue. My Python installation is that of Python(x,y) 2.1.17, which includes the same version of Python as yours, and I'm using a build of matplotlib from SVN, although I previously used version 0.99.0 without DLL trouble. On my machine, I found msvcp71.dll in several directories under C:\Python25\Lib\site-packages (including site-packages\wx-2.8-msw-unicode\wx), in C:\Windows\System32, and in several locations under C:\Program Files, but not in C:\Python25. There is a similarly-named msvcr71.dll in C:\Python25. I'm wondering whether and how msvcp71.dll is related to the traceback to the _path module, because the _path module comprises a .pyd (~= .dll) file. You might start Python, enter "from matplotlib._path import affine_transform", and see whether the import is successful. Are you able to run other matplotlib examples? Can you open a figure window? What backend are you using, and does the problem occur with other matplotlib backends, both GUI and non-GUI? ------------------------------------------------------------------------------ Come build with us!
