Currently, when you use an MSI installer (and possibly also EXE) for a Python module, it automatically detects the location of your various system's Python installations. This is very convenient. However, this can be a problem sometimes, if your Python installation doesn't conform to what's required by the installer. For example, if you want to install the module in a virtualenv: http://serverfault.com/questions/305008/installing-compiled-python-modules-on-windows-on-a-virtual-env The installer doesn't give you any option to manually enter a path of a Python installation, so you just can't install! The installer's automatic Python-finding mechanism should degrade gracefully; it should offer to automatically find your Python installation, but it should allow you to bypass it and type it in yourself.
I don't think it's necessary. People who want to get at the files can do an administrative installation, and put the files anywhere they like. Therefore, I won't work on this myself; somebody would have to contribute the code. It will be difficult to allow multiple simultaneous installations into different paths, which I think the OP would want - so even if the literal request from is satisfied, the actual issue probably remains as unimplementable.
