I have an issue reinstalling QuickBooks premier 2014 desktop as the licence number is not being accepted. Do I need an additional activation code as the product is no longer supported? If so how do I get one?
You can try calling intuit in the UK, but I seriously doubt they can or will help to get an unsupported version installed.
Once a product is past its designated support life as is your 2014 you cannot self authenticate for reinstall. You will have to call UK support during normal business hours and they will help you. Find the number from the "Contact Us" link and discuss not call any number publicly posted here on the forum as 99% of those are scams
