Yes, I agree with Fiat Lux - ASIA. Since we're unable to gather sensitive information on a public platform such as the Community for security concerns. That said, I highly suggest contacting our QuickBooks Desktop (QBDT) Technical Support Team. Also, they can guide you further with the registration process. Here's how:
 

  1. At the top menu bar click Help, then select QuickBooks Desktop Help.
  2. Select Contact us and then enter that you get Reminder prompts and Continue.
  3. Then choose either to Message an Agent or Talk to a Specialist.
