As the title pretty much says, whenever I try to “Indicate in Excel” I get hit by the error message “Interface not registered (Exception from HRESULT: 0x80040155).”. I have the Excel Addin tool installed as well if that will give any further information as to what is wrong.
I am just getting started with UiPath and I am trying to complete the first tutorial “Working with UI Automation”.
Any help would be appreciated.

Better late than never.

Pretty much the same solution as yours, but I repaired Microsoft Office and it works fine now. Figured if others have the same issues they have both options to pick from.
Cheers and thanks for your help
