Hi

How have you installed Orthanc and how are you running it?

Maybe what you want to do is to stop the Orthanc service and try to run it manually to check the output log more easily.

What you should do:

  • Open an admin shell (press Start menu, type powershell, then right-click on it and choose Run as administrator)

  • Type: Stop-Service -Name Orthanc

  • Once it’s stopped, use cd "C:\Program Files\Orthanc Server" , or wherever Orthanc is installed to navigate to that directory in the shell.

  • Execute Orthanc with .\Orthanc.exe Configuration\

    • Warning: simply executing .\Orthanc.exe will not work, because it will not pick the correct configuration and will use the default configuration.

You should then see the output log. Leave it running and check how it behaves. You may open http://127.0.0.1:8042/plugins to check if the plugins you need are displayed (the default auth is orthanc:orthanc)

(When done, press CTRL+C in the admin shell to exit Orthanc)

Let us know what’s displayed in the logs and how it goes

Hello! Today I was trying the application with the same setup and seems the problem is the python library. Initially I have python 13 installed which is not supported. Then I switched to Python 12.9 and this one also didn’t work. Finally I removed the file OrthancPython3.12.dll from Plugins directory and it worked. It also gave the same error when I try to start the application as a windows service.

Hi Diego

Your setup seems a bit messy, but glad it worked in the end :slight_smile:

How it works :

  • You need a system-level Python install that is accessible through the PATH or the other usual mechanisms that Windows provide to locate DLLs, as mentioned in the Orthanc Book

  • You need a matching OrthancPythonX.Y.dll in the plugins folder.

For now it seems that you’re using Python 3.12 with version 3.12 of the plugin, so everything’s fine.

Python 3.13 is probably compatible, too (there is no such thing as “Python 13”), but you need the corresponding OrthancPython3.13.dll installed in the Orthanc plugins folder, and it is perhaps not provided as a pre-built binary (I am mentioning this in case you really need to run 3.13 : it should be doable)

Hello,

I have just added support for compiling Python 13 for Windows in the mainline.

You can find the resulting precompiled DLLs on our download site. Check out the file OrthancPython-Python3.13-mainline.dll.
