I downloaded the Quickbooks Pro 2020 trial version and uploaded my company info. I purchased the QB disc at Best Buy. How do I change or activate my new QB in the trial version? Wouldn't let me change the product code, only the license number?
You have to uninstall the trial license and reinstall it to make sure you are key-in the license code and product code. The system will force you to submit your Intuit ID later as part of the installation process.
