Hi Haritha,
Thank you for contacting the Microsoft Community.
I understand the importance of being able to access the OnVUE application, especially when your exam date is approaching. Be untroubled by worries, let me provide you with necessary information.
Since your exam date is approaching, it's crucial to reschedule it first to avoid missing it due to the current issue with the OnVUE application. Make sure to reschedule at least 24 hours before your appointment date. If you fail to do so and miss the exam, you will be tagged as a No-show, and your payment will be forfeited. This step ensures you have enough time to resolve any technical issues and still take your exam without any penalties.
Meanwhile, to ensure your device meets the minimum system requirements, kindly review the Pearson VUE’s detailed information on what's required.
Moreover, please make sure the user account you’re using to log into your computer has local administrative permissions. For help on enabling administrative permissions, see documentation for Windows and Mac. We recommend using a personal computer rather than a work or company computer to take the exam. Company computers often contain software that can prevent the OnVUE application from launching.
Furthermore, it's important to configure your internet security and antivirus software to make an exception for the OnVUE Secure Browser executable file. Some antivirus software can cause performance issues, so consider disabling antivirus scanning while launching the application and taking your exam.
Additionally, ensure that your security software does not block the execution of JavaScript, Adobe Air applications, or Adobe Flash Player extensions.
If you still experience the same issue after following the technical tips above, we recommend contacting Pearson VUE directly. They possess the necessary access and tools to provide troubleshooting steps for OnVUE application issues.
Should you require further assistance from our end after contacting Pearson VUE, please send us your Pearson VUE case ID along with the other requested information through the private message that I initiated. This will help us explore all the other options if necessary.
I look forward to your response. Please note that if no response is received after two business days, the case will be closed and locked. After the case is locked, we will no longer be able to respond, even through Private Messages. Thank you.
Best regards,
