I have a project where someone has updated the UiPath.System.Activities to version 20.10.1, but my project is supposed to use 19.10.1.
Before you all say “just downgrade”, you should know that there has been added A LOT of functionality to the project, and doing so will give up 105 “missing activity” errors. The project runs fine om my Studio 20.10, but when I publish it to the ORCH 19.10 it won’t upload.
I think it’s because ORCH does not have the nugetpackage in this particular version.
I copied it to C:\Program Files (x86)\UiPath\Orchestrator\NuGetPackages\ActivitiesSource and that wnet fine.
However, the package must somehow unpack and register itself in ORCH.
