In order to troubleshoot this issue effectively, I will need you to provide the following information:
- What is your Operating System (Windows XP, Vista, 7, 8, 8.1, 10)?
- Do you have any security software installed (Norton, McAfee, AVG, etc.)?
- What version of RealTimes/RealPlayer is installed? (See https://customer.real.com/hc/en-us/articles/204039513).
The more details you provide, the better I will be able to assist you.
