Hi there!

I am pretty new experimenting with Orthanc.  
I just have installed the Windows version via the Osimis installer (OrthancInstaller-Win64-18.12.3.exe)  
Despite having all plugin libraries in the correct folders, none of them can be seen in the plugin list of the web explorer:

Looking into the log, the Plugins nevertheless seem to be correctly registered:

Hello,

This is unfortunately a known issue in Orthanc 1.5.1 with Edge and Firefox that has been fixed by the following changeset:  
[https://bitbucket.org/sjodogne/orthanc/commits/b89a4288d60521c924be884141d490d7ed938bef](https://bitbucket.org/sjodogne/orthanc/commits/b89a4288d60521c924be884141d490d7ed938bef)

Until Orthanc 1.5.2 is released, you can either downgrade to Orthanc 1.5.0, or use Chrome/Chromium that should work properly.

Sorry for the inconvenience,  
Sébastien-

Thank you for the quick response!

Works perfectly with Chrome. Great 🙂
