I am unable to add the UiPath Packages which I have downloaded from the marketplace nor find the package inside marketplace.
My Studio is also unable to find the package even after pointing to the folder directory.
I have downloaded the package from the market place and placed it inside a folder “C:\UiPathPackage” but when I try to find it under the manage packages section, I could not find it.
@Jackson_Hew : You should be able to see it in Studio - Legacy using the search keyword “excel extension”.
Please note that this package has not yet been migrated to .Net 6.
Cannot add a package that contains System.Activities.ViewModels.

@Jackson_Hew :
You are using UiPath Studio 2021.10.8. It contains options to create “Windows” as well as “Windows-Legacy” type of process. “Windows-Legacy” processes use .Net 4.6 which is out of support from Microsoft so this type of process is called Legacy in UiPath Studio.
The package “Excel Extension Activities” is created in .Net 4.6 and has not yet been migrated to .Net 6 so you can run this package under “Windows-Legacy” only.
“Windows-Legacy” value can be selected from the “Compatibility” drop-down while creating a blank process. You can make this selection from the screen as shown in the image by @Yoichi .
