Unable to ZIP excel files, getting error

Hi i am using BalaReva zip activity, after given an input and started to execute getting an error msg like " Zip: Could not load file or assembly ‘Ionic.Zip.Reduced, Version=, Culture=neutral, PublicKeyToken=edbe51ad942a3f5c’ or one of its dependencies. The system cannot find the file specified. "
My Uipath version is 10.4.

@balupad14 please help me to fix this issue


As an alternative can you try with Zip activities available in UiPath Studio?


Or we can wait until fix release by Balareva
