PlusServer 2.9.0.20260326 pb with installation (2 computers) and Optitrack streaming (1 other computer)

Dear Slicer and Plus team,

I have tried the last version PlusServer 2.9.0.20260326 win64.exe but I encounter an error on two different computers when trying to launch the software saying :
error with the vtkAddon.dll ...

On a third computer I succeeded in installing this version but when streaming with Motive Optitrack I have a server failure with this log :

Thanks, I've found the source of the error. I'll let you know when it is fixed.

I've fixed the issue. The nightly link hasn't been updated yet but you can find an updated installer here: https://github.com/PlusToolkit/PlusLib/actions/runs/24841873916/artifacts/6605533680

Thank you so much, the install works fine and I should be able to test with Optitrack on Monday at the latest.
Best !

Hi Kyle,
I confirm that the install works, however the connection to Optitrack does not with the same error message :

That looks like an issue with the config file.
You need to add a "Calibration" attribute to the device. See: https://github.com/PlusToolkit/PlusLibData/blob/master/ConfigFiles/PlusDeviceSet_Server_OptiTrack_Profile.xml#L13

I think for duo and trio devices the path can be empty since the calibration is integrated in the camera.
