If your recipients have issues viewing 3D PDF file you created using 3DVIA Composer, here is the solution I pulled straight from Knowledgebase (S-024436). While I continue to hunt for simpler solution, this worked for me in the meantime.

Question: An error message displays when opening a PDF with an embedded 3DVIA Composer file even though the 3DVIA Player Plug-in for Adobe® Reader® is installed, why?

Answer:
1. If only Adobe® Reader® is installed, the 3DVIA Player Plug-in for Acrobat Reader will properly install and no error will be seen.

Note: If Adobe Reader 9 is installed please refer to solution, S-028884.

2. If only Adobe Acrobat is installed, the error will display. To resolve this:

- Browse to "C:\Program Files\Dassault Systemes\3DVIAComposer\6.2\Plugins\Acrobat\Plug_Ins"
- Copy files "3DVIAPlayerControl.dll" and "3DVIAPlayerReader.api"
- Paste them into "C:\Program Files\Adobe\\Acrobat\plug_ins"

3. If Adobe Acrobat and Adobe Reader are installed, the error will only display in when opening a PDF in Acrobat. To resolve this:

- Browse to "C:\Program Files\Adobe\\Reader\plug_ins"
- Copy files "3DVIAPlayerControl.dll" and "3DVIAPlayerReader.api"
- Paste them into "C:\Program Files\Adobe\\Acrobat\plug_ins"
