Question: How to get Excel Add-In Working in Maple Flow

Hello, I am trying to get the Maple Flow add-in for Excel working and am following the step-by-step directions in Chapter 7.3 of the Maple Flow manual. My computer meets the requirements listed in Chapter 7.2.

After selecting the WMIMPLEX64.xla file as directed in the procedure, I get the following error in Excel:

The Excel toolbar also does not show the same six icons in the add-in toolbar that are shown in the Maple Flow manual (see the manual excerpt below); it appears that the missing icon is the key icon that would initiate the Maple Flow worksheet wizard.

If anybody has been able to get this to work or has suggestions to resolve these errors, I would appreciate any advice.

Thanks
