Hopefully someone can help. I'm using a PC, using Safari 33.0.3 (update available, I know), running Windows 7.
Right now, version 188.8.131.52 Flash Player is installed. I'm able to download the install file, open it, and the security window comes up
and I hit 'run'. Then the user account window opens and asks if I want to make changes and I hit yes.
Then the Install Flash Player window comes up with just a gray background and nothing happens. Tried multiple times, closed Firefox,
followed all the troubleshoots I could find. I even uninstalled Flash Player to see if I could load from scratch and the same install window
comes up and nothing happens.
In Firefox, if you choose Help > Restart with Add-Ons Disabled, does the problem go away?
Also, have you tried rebooting your computer?
