Unattended robot: Cannot create unknown type

Dear community members, I have developed and published a process on one PC where I have Studio. I then copied the published package to VDI, where I have only unattended Robot installed. I don’t have an orchestrator. I try to run process from tray, it is discovered, everything should work properly, but after I press Run process button, I get this error:

UiPath Robot Tray

An error appeared while executing SmartScheduler

Error message: Cannot create unknown type ‘{http://schemas.microsoft.com/netfx/2009/xaml/activities}Variable({http://schemas.uipath.com/workflow/activities}DatabaseConnection)’.


Apparently robot fails to update Database activity package. How to permanently resolve this problem?

this could help you buddy @NotFranmax


Thanks, I have already went through forums and this unfortunately is not the solution I see. But now I have found another one. Apparently I have no access to

MyGet.org **
NuGet.org **

I will whitelist these domains and come back with news.

make sure you have uipath.database.activities dependecy installed.
