I am trying to install Microsoft Project Professional 2019 64 bit (volume license) on a system which already has Microsoft Office Professional Plus 2019 en-us. I received an error message that "We can't install. To install this product, first uninstall Microsoft Office Professional Plus 2019 en-us"
My concern is that the user needs Microsoft Office Professional Plus 2019 en-us and as such, we cannot uninstall. How do I go about this.
