Could not load file or assembly 'ClosedXML, Version=' How to remove the reference of this version from the project

Read range (Settings and Constants sheets): Could not load file or assembly ‘ClosedXML, Version=, Culture=neutral, PublicKeyToken=fd1eb21b62ae805b’ or one of its dependencies. A strongly-named assembly is required. (Exception from HRESULT: 0x80131044)

How to remove this reference from UiPath Project? The version doesn’t exists in nuget, so I have downloaded the latest version 0.95.4 but the project still references to the old version


Hi @Praveen8008

Welcome back to UiPath forum.

Could you please send me the picture of the dependencies, which you are using in your project.

Hi @vignesh.ks ,

Please find below the screenshot,

Update the dependency from the manage package. it shows the earlier version because it is not upgraded successfully.
Or you want to uninstall it you can uninstall the dependency from the manage package as well.

Okay, Please update the dependencies mentioned below,

  1. UiPath.Excel.Activities
  2. UiPath.MicrosoftOffice365.Activities

Update the package and try running the process.


Happy Automation


Thanks @vignesh.ks . It worked after upgrading both the above said packages. Earlier, I have upgraded only the excel.activities package.
