Occasionally someone will inadvertently install Velixo NX (for Mac and Excel Online) on a system running Excel for Windows:
Here is how to uninstall Velixo NX.
On the Excel toolbar, go to the Insert ribbon and select My Add-ins:
From the Office Add-ins windows, click the three dots next to the Velixo add-in...
... click Remove from the menu..
... and then click Remove on the displayed dialog:
You can now download and install Velixo Reports Classic for use with Excel for Windows
Note: It is possible for Excel files to maintain a reference to an add-in even after the add-in has been uninstalled. When this occurs, it is necessary to manually remove that reference.
In Excel, click on File -> Info -> Check for Issues -> Inspect Document:
On the Document Inspector window, check the boxes for
Task Pane Add-ins
and then click Inspect.
If the Document Inspector reports that there are add-ins still found...
click Remove All
save the workbook
open the workbook
This should remove any reference to Velixo NX that was still maintained in the workbook.
