Orange Not Loading at all in Windows

[Killorito]

What's wrong?

I have installed Orange from the Orange website (the application, not pip). I have extracted the file, and I can see the execute of the file. However, every time I click on the file, it does not load. I made a new account on my windows 10 machine, and it could run on the new account. I have deleted orange from the main account and re-installed it, but it didn't work. I have searched for any remaining files of orange so that I may get the cleanest install possible, but it still does not work.

How can we reproduce the problem?

Unfortunately, I cannot tell you how to reproduce this as it just occurred on my system.

What's your environment?

• Operating system: Windows 10, the latest update
• Orange version: 3.30.1
• How you installed Orange: I went into the orange website, downloaded the file from: https://orangedatamining.com/download/#windows. I then went and followed all the steps, and selected to have a shortcut in the desktop. After, whenever I clicked it, it did not load.

Might I ask was it just the shortcut that didn't work? Did it work if you ran Orange from the start menu?

[Killorito]

@ajdapretnar , it really doesn't matter on the shortcut, because everything I try to do to make Orange start, doesn't. I have even restarted my laptop, and the shortcuts and execute files that are made by orange don't work on launching it.

[ajdapretnar]

Ok, could you maybe open Orange Command Prompt (it is a special program on Windows) and run python -m Orange.canvas -l 4 and post the output here?

Hi @ajdapretnar , the output i get is:

@ajdapretnar , also on a side note. I do not use Anaconda, but just made orange download miniconda for it to work. This is because I am using python that I downloaded myself.

[ajdapretnar]

My guess is you are using 32-bit Python, which doesn't work with Orange. You'll need 64-bit. But I didn't quite understand when did you download Miniconda. Was it for the new user or for the old one, but it still didn't work?

[Killorito]

@ajdapretnar Miniconda was downloaded when i was downloading Orange. However, I do have the 64-bit version:

Python 3.9.7 (tags/v3.9.7:1016ef3, Aug 30 2021, 20:19:38) [MSC v.1929 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

My guess is that there is something wrong with the initialization of orange. I have already re-installed and rebooted my laptop many times, but it does not work!

That seems suspicious. It's mixing environments from Orange local env and global Python38. Do you by any chance have PYTHONHOME or PYTHONPATH environment variable set? Run echo %PYTHONHOME% and echo %PYTHONPATH% in the Command Prompt and post the output.

[Killorito]

@ales-erjavec , the output for the echo %PYTHONHOME% is: %PYTHONHOME%. The output for echo %PYTHONPATH% is %PYTHONPATH%

[Killorito]

@ales-erjavec I was having Path issues before, and so i deleted any python instances in my path, and reinstalled all of python. I was using Anaconda back then, but i deleted everything from Anaconda and python (anything i could find in my folders i purged).

[ales-erjavec]

Can you try running python -s -S -m Orange.canvas -l 4

[Killorito]

@ales-erjavec Hello. I get (from:python -s -S -m Orange.canvas -l 4):

C:\Users\...\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\python.exe: Error while finding module specification for 'Orange.canvas' (ModuleNotFoundError: No module named 'Orange')

[ales-erjavec]

Sorry. Can you try running python -s -S -m Orange.canvas -l 4 from the Orange Command Prompt

[Killorito]

@ales-erjavec Yeah sure. Here is the response:

C:\Users\...\AppData\Local\Programs\Orange\python.exe: Error while finding module specification for 'Orange.canvas' (ModuleNotFoundError: No module named 'Orange')

[ales-erjavec]

Can you try again with just -s i.e. python -s -m Orange.canvas -l 4

[Killorito]

@ales-erjavec Wow, it worked!! It launched Orange!

How did it do that though?
