I am trying to install Flash player in Firefox (latest version) and windows 8 OS (rather unimpressed with it but...). The program downloads fine. It prompts me to run it and that goes fine. It asks for permission to make changes. I grant it. The it starts but all I see is a an empty gray box. No writing, no status bar, simply a dark grey/black box with a blue frame. It never does install and work.
I have read through the installation troubleshooting guide and tried some of the suggestions for windows but it was no help. What should I try next?
PS This is not an easy forum system to use or get help on. None of the communities seem like logical places to post this question.
