Hi I'm not a developer but have a developer working for me that hasn't been able to resolve this issue.
We have a web based application that invokes excel. The application was amended recently and successfully worked in the test "environment". i.e. folder \demo
this was moved to a live "environment" folder wwwroot ON THE SAME SERVER and not we are getting the "Could not load file or assembly 'Microsoft.Office.Interop.Excel, Version=14.0.0.0" in the live environment. The developer says he just copied all files and updated the database connection link. It still runs on the same machine in the test environment. any ideas ? Many Thanks.
