Okay I can tell no one is gonna reply to this...
This is a user-to-user forum. With very few limited exceptions NO ONE here works for Adobe and it ISN'T staffed 24/7. We're just users who volunteer out troubleshooting skills and time. We have jobs, families and lives of our own, so it can sometimes takes a while for a reply.
Download the Adobe Flash Player installer directly by right clicking the following links and selecting "Save target as" (IE) or "Save Link as"(Firefox).
Save the files to your Downloads folder - DO NOT run anything yet.
Reboot your system.
BEFORE opening anything, go to the Downloads folder and run the UNINSTALLER to remove all instances of Flash Player.
Next, run the ActiveX installer, and then the (other browsers) Installer.
First of all, I never ever urged any of you to answer my question. I was only expressing my frustration... So quit saying something like "this is a blablabla forum", okay? I know most of you are volunteered.
I will post the result after trying out your method. Thank you.
EDIT: This works. You are my life saver. You made my day!
