Recently, we ran into an issue installing the data integrity hotfix for Plant 3D SP 1. The issue is that when opening the report creator, the PnPDataObjects.dll cannot be loaded. Users get a warning dialog like this:
The source of the problem is that certain actions in Windows can mark some files as unsecure. Meaning that until you indicate that they are safe, Windows will not load them. For example, we’ve all seen the warning in Word that a document was downloaded from the internet.
What happens is that if you click through to the contents of the .zip contains the hotfix, and then copy+paste them into the installation directory (C:\Program Files\Autodesk\AutoCAD Plant 3D 2013 – English), the PnPDataObjects.dll is marked as unsafe.
To correctly install the hotfix, you must extract the zip first and then copy+paste the contents.
