Solution is simple (in theory too). Replace CTR with "Normal" MSI install.
The not simple part is it depends on how you got a CTR installation in the first place. If it is Office Starter, there is no fix. MS does not offer Starter installation files to end users, only to manufacturers for "OEM" installation.
The other way to get stuck with CTR is via an online purchase. MS has setup the download sites to check your online connection. If the download site identifies that you have a high speed connection that will allow you to run CTR satisfactorily (again, in theory),
the download will default to CTR rather than MSI installation.
In this case you can go back to the download site, log in to your account there and look very carefully, there should be a link to an option to download the MSI install file. It may be hidden behind an "Advanced" link or button.
Once you get the MSI install file, you can uninstall the CTR, reboot and install the MSI.
