Anyone else getting this when excel is open and user selects an excel file in the vault. I'm thinking it has to do with the preview tab, and with it attempting an ole access to excel that is already opened on the users machine. Thought I saw something online about this recently but can't find it now. This is in SolidWorks 2014 SP5 and Enterprise SP5 for vault and clients.
I finally found the SPR reference I was looking of on this - SPR 735225
