There is a know problem with the Plant 3D 2015. When you create the deployment with the Object Enabler (OE) and try to install to a client machine it fails.
To workaround the problem, you will need to create a new deployment and uncheck the box to install the OE.
How to deselect the option that installs the OE:
- Find the "Autodesk AutoCAD 2015 section, click the down triangle (it's a toggle) to expand out the details / options.
- Uncheck the "Autodesk AutoCAD Plant 3D 2015 Object Enabler" selection.
- Click the up triangle to sync up the options.
- Click Create to start creating the deployment again.
If you're installing both Plan 3D and AutoCAD onto the same machine the OE is not needed.
