Could not load file or assembly 'DocumentFormat.OpenXml

Question

I\'m keep getting this error is VS2013

Could not load file or assembly \'DocumentFormat.OpenXml, Version=2.0.5022.0, Culture=neutral, PublicKeyToken=31b

Answer 1

I had this problem because I had a new version of the .dll installed on my computer running on localhost and my server was running an old version of the same .dll

I just updated it and everything works well after that.

In your case, install the DocumentFormat.OpenXml version 2.5 available in this microsoft link
