- Do you have MS Excel (or PowerPoint if you are attempting to manage a PPT template) on your machine?
- If so, which version exactly? Is it virtualized?
Please refer to the following page for details about requiremets: Requirements for NPrinting 14 and following versions – Customer Feedback for Vizubi
- Microsoft Office 2003, 2007, 2010, or 2013 (32 or 64 bit) only on the computers on which templates will be created.
- NPrinting will function properly on both physical and virtual machines. In both configurations, NPrinting requires that QlikView and Microsoft Office (for development only) are installed on the same machine. NPrinting will not function if it is installed on one machine and the virtualized applications are installed on different machines.
Alos, there is an issue with registry setting that can cause this error (I have encountered it myself) with certain version of office (2013)
