Orange Canvas will not open Windows 7

[dstarobin]

Hello,

I've attempted to install Orange (Win7, 64 bit), but it will not open. I have Python 2.7 as well as Python 3.4 installed (3.4 installed with Orange). Nothing happens when attempting to open the program. I've rebooted as well. I see Orange in C:\Python34\Lib\site-packages\Orange. Any help is appreciated.

Thanks.

If you open command prompt (cmd.exe) and paste in:
C:\Python34\python.exe -m Orange.canvas -l 4
What does it output?

Thanks for your quick response and sorry for my long delay. The message reads:
"Error while finding spec for 'Orange.canvas' < class 'ImportError'>: DLL load failed: %1 is not a valid Win32 application.

Ah, yes, due to NumPy being only officially available compiled in 32-bit mode, Orange only supports 32-bit Python on Windows. If you had Python preinstalled, you should install the one from Orange installed into another folder, like C:\Python34_32, and then also install Orange there.

NB: This repository/issue tracker is actually for Orange 2.7; Orange3's is here.

Ok, thanks for your guidance. I'll do that.

Thanks again. In uninstalled Python 3.4 as well as Orange, then reinstalled via Orange's distribution. It worked perfectly.
