When I try to insert it, I constantly get the "Cannot insert object" error. It seems to be a known issue with former Excel versions, but I couldn't find any support for 2016.
Has anyone been able to make this work?
Here are screenshots:
This appears to be intentional behaviour from Excel 2013 onwards. From this article:
This issue occurs because some scriptable controls are made obsolete in Office 2013 for security reasons. This is by design, and these errors are expected.
There is a workaround posted in that article which involves editing the registry to make these controls work again.
