I am getting below error when my bot is running

I haven’t tried this, since you mentioned Macros within Excel Application scope,it’s worth a shot:

Unable to cast COM object of type 'System.__ComObject' to interface type

Hi Daniel, I unchecked the Visible property of Excel Application Scope from which the ExecuteMacro Activity was being called. And it worked for me. The issue in my case was around the screen update during macro execution. Regards, Rajni
