Excel activity missing after package update

Hi,
I have a project with Excel activities which was working fine. After I did a Excel activities package update to 2.6.2.0 version, when I try to open the same project, I am getting the below error.
" Could not resolve type ‘Error’ because could not find one or more of its type arguments. Row: 171, Column: 28
Could not find type ‘WorkbookApplication’ in namespace ‘http://schemas.uipath.com/workflow/activities’. Row: 171, Column: 28
Could not find type ‘ExcelApplicationScope’ in namespace ‘http://schemas.uipath.com/workflow/activities’. Row: 194, Column: 32"

When I check the activity pane for excel activities, it is missing even though the Excel activity in packages window is showing Installed.

Please help me resolve this error.

Hi @Suchitra_C,
Welcome to the Community!
Which version of Studio do you have? Have you tried to downgrade excel package and check if activities shows up?

Hi
I have community edition version 2018.1.4.
When I downgrade to excel package 2.5.4.0, the activities are present in studio.

This version is faaaar away from current one (2019.7). Please update it to newest version and all should work.
