could not load file or assembly 'ClosedXML, Version=

May 10, 2012 at 10:39 AM

Following is the unexpected error we are receiving.

Could not load file or assembly 'ClosedXML, Version=, Culture=neutral, PublicKeyToken=fd1eb21b62ae805b' or one of its dependencies. The system cannot find the file specified

we are using ClosedXML for .Net Framework 3.5 version in my SharePoint 2010 environment. I verified that the application's bin already contains ClosedXML.dll and DocumentFormat.OpenXml.dll.

Any idea ?

Hi MDeLeon, 

Thanks for your reply, can you tell me what could have been the cause of this error. Is there any specific set of data which the dll is not able to parse or something ? It is our client's production environment and untill next release i can not redeploy the component refering to latest dll.

appreciate any help.

You should check the permissions on those .dlls. Also check out:

If that doesn't help then I don't know what could be wrong there.
