Issue Details

I am using the LabVIEW Report Generation Toolkit to generate Microsoft Word or Microsoft Excel reports. I have custom formatting that I need to apply using Property and Invoke Nodes.

  • When I try to select a class for Property or Invoke Nodes, I do not see the Microsoft Excel or Microsoft Word type libraries.
  • I am getting error -41106 word would not open when using the Create Report VI
  • When I load existing code, I cannot edit the existing nodes. Instead, my ActiveX Property and Invoke Nodes show No Properties or No Methods.
  • When I drop a property node or invoke node on the block diagram, there are no classes or methods to select. I also cannot modify property nodes within LabVIEW examples.
How can I access these properties and methods? 


This behavior can happen if you use LabVIEW 32-bit and Microsoft Office 64-bit. For example, Excel 2016 64-bit will not work with LabVIEW 2018 32-bit. To solve this issue, use LabVIEW 32-bit with Microsoft Office 32-bit , or, LabVIEW 64-bit with Microsoft Office 64-bit.

Additional Information

Refer to About Office: What version of Office am I using? for steps to check the bitness of your Microsoft Office installation.

While it seems possible to use LabVIEW 64-bit with Microsoft Office 32-bit, it is recommended to have matched bitness between LabVIEW and Microsoft Office.
