Greetings, @Shawan Sharif.
I appreciate you coming to the Community with your question about downloading your ProAdvisor Certification.
Before digging further, have you tried the steps listed in this article below in the Get your certificates and badges section:
ProAdvisor and QuickBooks certification courses
If you have, let's try clearing your browser's history or restarting your computer.
In addition, I recommend sending a picture to us of what the download looks like when opening it.
I'll be waiting for your response!
