Detected Office 2019 C2r Retail Could Not Be Converted To Volume ✦ Verified Source

Another solution is to use the Microsoft Office Deployment Tool (ODT) to convert the C2R retail installation to a volume-licensed installation. The ODT is a free tool provided by Microsoft that allows administrators to customize and deploy Office installations. By using the ODT, administrators can create a custom configuration file that specifies the volume licensing agreement and other settings necessary for the conversion.
