I want to add PlantUML into WORD 2010 64 bit. Did as all suggestion but still failed with message: "The macro cannot be found or has been disabled because of your Macro security settings". My system is: Windows 7 61 bit, WORD 2010 64 bit. Have you ever fix this? I already check solution about this issue but still failed. I think it belongs to 64bit/32bit compatible. Please check it.
