Hi Noud,
I just want to close this out. This is what Microsoft said officially:
Hi Partner,
Thanks for getting back, and yes I’m absolutely using the Visio Pro 2013 both X64 and X86 to test and as I said in my last reply, it is
not supported in Visio 2013, neither X64 nor X86. The WBS Modeler 1.0 is the one that you downloaded and it is only compatible with Visio Professional 2010 or Visio Premium 2010 • Microsoft Office Project 2003 Service Pack (SP) 1 or later •
Microsoft .NET Framework 4.0 like Visio 2007. WBS Modeler only supported in Visio 2007.
We are sorry for the inconvenience we have brought because of the incompatibility. Your kindly understanding is much appreciated.
Should there’s any concern, please feel free to tell us as usual.
Best Regards,
Mona Li
