Error message : Cannot create unknown type

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)’.


@MiK Install the excel package

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…

Thank you guys!
I will try installing.
