I have a collection of realplayer videos originally downloaded in 2016-2018 onto an external hard drive. I just retired my windows 10 PC and replaced it with a windows 11 PC and installed realplayer 20. I get a message that I need Flash to play these videos so I found a download for flashplayer 32 and installed it. Same problem. Then I tried realplayer 18, same problem. Then I tried to convert my old videos in realplayer to another format and all attempts failed. How can I view my old realplayer videos on my new windows 11 PC?
