Hi, I encountered below error when I executed Robot.
The automation worked without any problem when Studio was installed, but after I removed Studio it doesn’t work now.
I published the automation with different laptop which Studio is installed.
The version of Studio and Robot is same, 2018.4.3.
Should I reinstall Robot or republish the automation?

An error appeared while executing (automation name 1)

Error message: Cannot create unknown type ‘{http://schemas.uipath.com/workflow/activities}ExcelApplicationScope’.

An error appeared while executing (automation name 2)

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

Hi,

Make sure you have installed Microsoft office package in those computers. In order to excel related activities to work properly, you should have them installed…
