I have the Chemistry add-in installed on our server with Word 2010. It installed properly and loads when Word opens, however when we try to create a new structure, it throws an error after a second saying it cannot load a file or assembly.

The structure editor comes up after you clear the error, but once you create the structure and confirm the label, it throws another error and the structure does not appear in the document:

Is there any troubleshooting that can be done for this?
