[Numpy-discussion] Installation problem with Numpy 1.3 on Windows AMD64

Hi! I just upgraded to Python 2.6.2 (from 2.5) on Windows AMD64 in order to use Numpy 1.3 for AMD64 and got the following error: - pythonw.exe has stopped working Numpy was installed both per-machine and per-user but the error persists. Python 2.6.2 works without Numpy. Any ideas? Dinesh
