Hi, We have received a lot of queries about not being able to download course completion certificates or PDU certificates so here is how you can avoid this issue: 1. When you click on Download Certificate, you will see a pop-up to download the certificate. However, usually pop-ups are disabled on browsers. 2. Please click on this link for a procedure to enable pop-ups on different browsers: http://www.wikihow.com/Disable-Popup-Blockers 3. Post following the procedure, please close the browser and open it again, you should be able to download your certificate. 4. If you are still facing any issues, please raise a ticket on your Simplilearn account with a screenshot of the issue and we will get back to you at the earliest.
