Problem: Reference 3D models fail to update using batch.
Solution: Verify that the folder C:\Windows\sysWOW64\config\systemprofile\Desktop exists if you are using Windows 7 (64-bit) or Windows Server 2008 R1. Have your system administrator create the Desktop folder with full permissions if it does not exist. Microsoft Excel does not function properly without this Desktop folder; therefore, the Reference 3D projects will not update in batch.
