If your installer looks like this
then the issue is that the Microsoft Office365 Access Runtime is conflicting with the installed version of Office on the computer.
To resolve, click the X in the top right corner. Confirm that you want to close the Installer.

Then click OK.
This will start the uninstall process. Follow the prompts to complete the process.
