Update to Adobe Flash Player 18 get blank screen

[Guest]

My operating system is Window 7 Professional, browser is Mozilla Firefox 38.0.5(x86 en-US), Flash player version 10.0.2.

I bought my new Dell desk top end of last month, after that I reinstall my ‘Adobe Creative Suite 4 Design Premium’, so currently I have Adobe Flash Player 10 ActiveX, Adobe Flash Player 10 Plugin, Adobe Media Player, and Adobe Reader XI (11.0.11).

Sometime when I am using the Firefox, I get the following messages :

“Error message from Adobe Flash Player 10: An ActionScipt error has occurred: VerifyError: Error #1053: Illegal override of play2 in org.osmf.net.httpstreaming.BaseHTTPNetStream.”

“Warning: Unresponsive plugin: Shockwave Flash may be busy, or it may have stopped responding. You can stop the plugin now, or you can continue to see if the plygin will complete.”

When I select continue, I get ‘The Adobe Flash plugin has crashed’.

When I follow the instruction to install Adobe Flash Player 18 according to https://helpx.adobe.com/flash-player/kb/enabling-flash-player-firefox.html, then I get the blank screen from Adobe Download Manager.

My Mozilla’s Add-on’s plugin status show outdated for Adobe Flash Player 10.0.2.54, Java Runtime Environment (NPRuntime Script Plug-in Library for Java™ Deploy) 8.0.40, Adobe Reader 11.0.11.18, Java Runtime Environment (Next Generation Java Plug-in 11.40.2 for Mozilla browser) 8.0.40.

How can I update my Adobe Flash player and reader?

Please try the offline installers at the bottom of the installation troubleshooting guide, here:

I did try the above 'offline installers' earlier many times, but this only brings me back to the 'Update' 'Adobe Flash Player' and then eventually to the blank 'Adobe Download Manager'.

Do I need to uninstall the Adobe Flash Player 10.0.2.54 before I can install the latest Adobe Flash Player?

You shouldn't under normal circumstances, but it seems like a reasonable next step.

This is the nuclear option, but I don't want to keep sending you in circles.  Hopefully this resolves it for you.

Once you've completely removed Flash Player and all the associated registry keys and stuff, just run the current installer again. 

If you're still stuck, the installer logs would be very helpful.

Where do I find the Flash Player installation log on Windows?

I did the 'How do I do a clean install of flash player' https://forums.adobe.com/thread/928315, followed every steps to uninstall and delete the relevant files.  

Then I  install the Flash player (get.adobe.com/flashplayer), when I run flashplayer18_ha_install, I eventually get to the blank 'Adobe Download Manager'.

I checked the installer logs: C:\Windows\system32\Macromed\Flash\FlashInstall.log and C:\Windows\syswow64\Macromed\Flash\FlashInstall.log, they are empty.

So I am back to square one.

However, when I use chrome instead of firefox, I have no problem using the 'video' plug-ins.

Are you able to proceed with the offline installer?  Links are at the bottom of this guide:
