Organizations can purchase Microsoft Excel via an Microsoft 365 subscription or by purchasing it outright (known as the .msi version).
​
Customers that receive this error are typically using the .msi version of Excel build number 16.0.4***.1001. Organizations that install the .msi build of Excel do so by purchasing a license that does not include regular feature updates (such as support for newer API's). Only security patches are delivered to .msi builds. 

Build 16.04***.1001 has affected our application. We've reached out to Microsoft and they did not have a solution.

If you are affected we recommend you upgrade to an Office 365 subscription from Microsoft. This will ensure you have a version of Excel that receives regular feature (API) updates.

Alternatively, you may use CloudExtend Excel for NetSuite online by creating your spreadsheet at www.office.com. Our add-in functions identically whether it is used on the desktop or in the browser.
