I have the OpenXML SDK installed on my development machine, and I have written a webpart solution that basically creates an excel file using the OpenXML dll. This solution is a full farm solution not a Sandbox solution.
When I deployed on my PC all is ok, as I have the OpenXML SDK installed, and all the revent dll's required for my webpart is in place on my PC. However when I deploy my WSP to the live server, it doesn't have the SDK installed.
How do I ensure the OpenXML dlls are available on the live farm without having to install the OpenXML SDK on each server in the live farm. There must be something I can do within my solution to ensure the dlls are available.
