Hey everyone,

I try to start a process from the orchestrator, but I face an error given below:

System error at initialization: Cannot create unknown type ‘{http://schemas.uipath.com/workflow/activities}ReadRange’. at Source: System.Xaml

I believe its about the excel package (since its giving the error on readRange).
Any idea why this is happening, the package I used to develop this process is not installed on the orchestrator packages, could it be the reason? Or any other suggestions?

Check whether Excel is installed in the Robot machine if you are using Excel Application Scope / Excel Read Range activities

Hope this helps you

Thanks

Ofc excel is installed, my other processes work on this machine without any errors, I only encountered this issue here.
