Are you using ArcFM at your organization? I've seen this type of error before and, in my experience, it has been related to the absence of a required ArcFM GUID within the registry for the particular version of ArcGIS and ArcFM being used. If you are using ArcFM, which specific product do you have installed on that 1 machine and which version of the software are you using?
