I’m using a learning trail from the Academy.
Where the instructor ask me to use Click activity but the activity wont Indicate the Excel.
I have the Add-in installed correctly.
I managed to automate the data tables without issue.
I have the file opened.
But it is giving this error where it’s saying it’s not attached
@Johnrey_Gabarra,
That’s abnormal behavior of Studio. Try Restarting studio and Excel file as well.
Thanks,
Ashok 
I don’t know if it helped @Johnrey_Gabarra, but it didn’t work for me. I’m facing the same issue at the same point in the academy course, and nothing seems to work. I even downloaded the academy solution project to check if my project had a problem, but it dropped the same error. I’m completely stuck at this point. Any further ideas?
God help me, after days of research, I found a hint that UiPath has an issue working with files stored in a OneDrive folder. I copied my project to a local folder and suddenly it started working properly. I highly recommend including this in the academy material, however fun it was to lose my mind on it
