Quickbooks Desktop Pro
My hard drive crashed, I had Desktop Pro 2018 installed and backed up onto an external hard drive. Problem is I can't find the product key. The only software I can find is Desktop Pro 2015 that has a product key. The account I used to register software has long been deactivated so can't log in. None of by backed up company files will import into the 2015 due to being a newer version. Is there a way to get my 2018 product key or what are my options to open my backup files. I can't afford to upgrade to new version and need to access these files as soon as possible.
