Event receiver was deployed into sitecollection using powershell and site feature was activated. Using powershell , i am able to see ER is attached to library. However , it is not firing: Event manager error: Could not load file or assembly 'yyy', Version=188.8.131.52, Culture=neutral, PublicKeyToken=xxx' or one of its dependencies. The system cannot find the file specified.
PS: While deploying ER using Visual Studio in the same sitecollection , ER is working fine
