Edp Excel Activities

As of November 17, 2020 (Today's update):

1. Clicking download results in a 0 byte file.

2. Manage Packages cannot find this Custom Activity

Can you clarify how to get these custom activities or if these activities are available elsewhere?

Hi, I'm trying to use the "SaveAs WorkBook" to save my current excel with a new name that contains a variable. I do this at the end of my excel application scope but I have the error "SaveAs WorkBook: Object reference not set to an instance of an object."

I'm trying to save it as "C:\temp\ToUploadDocsToAgresso\" + FileNewName

Where FileNewName is the variable that contains the code of the project to wich the excel file must be linked. 

How I must use the activity?
