Exception in Factory Design Utilities when leaving the 'publish asset' window
04:00 22 Dec 2025

I'm getting an exception in Factory Design Utilities when after creating a factory asset, I want to leave the publish window by pressing either OK or Cancel. I'm getting a 'System.IO.FileNotFoundException: Could not load file or assembly 'System.Configuration.ConfigurationManager, Version=9.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The system cannot find the file specified.'

I've tried to uninstall both FDU and Inventor and reinstalled both but with the same result.

I find it strange that I FDU is looking for a ConfigurationManager 9.0 version whilst a ConfigurationManager 8.0 is loaded (zie below).

What could be the cause for this exception?

Thanks,

Mark
