You have to be patient when it comes to Flash updates. They sometimes take an unusual amount of time to configure. As an alternative you could save the download to your system, close all open windows including browsers, and then install from the stored location. This protocol does alleviate the reference of the dedicated browser referred to by RC. DA

First guess: Are you installing the correct version; I.E. vs. Non-I.E.? If you are doing a "run-install" you absolutely have to be downloading the proper version. If you are doing a "save-install" you can use any browser to download-save-install either version, but it will only effect the target browser.. In my case I have FF, Opera, Google, SlimBrowser and I.E.9 installed on the system so I have both versions of Flash installed. Use the tool below to uninstall whatever you currently have installed. Then be triple sure you install the correct one. DA Here is a link that might be useful: Flash Uninstaller

Thanks for the responses and help. I am not using antivirus and removed the the antivirus before my Adobe problems. I checked/installed updates to Windows and IE. I went to Adobe.com and installed/reinstalled. This morning the issues seem partly fixed. When I am on a web page, such as Yahoo, whether in IE or FF, some of the boxes display and some don't. If I go to a web page page, like Yahoo's tech page, that has mostly boxes that have videos in them, I see the text in the boxes but they are otherwise blank. If I click on the box a video then starts playing. I know this isn't how it's supposed to work, but it's better than it was yesterday. Maybe if I wait till the next Adobe or Windows update it will sort itself out? Thanks for the suggestions. If you think of anything please let me know. I think I will put this laptop away for a week or two and use my Win7 laptop instead. I'll check on updates the next time I get it out and hope for the best.

Well, that's a loaded question. Do you need Flash? It's basically built into many browsers now (Microsoft Edge, Chrome and derivatives) so you don't need to "get it". For Firefox and IE, you still need to download separately, but make sure you're actually using sites that need it. It's probably the most common way to get a virus browsing the web today and is a major pain to keep installing updates (sometimes daily) and restarting your browser to get the new version. If you don't need it, it's pretty simple to not install it. If you do need it, or it's part of the browser you're using, you should consider getting a flash blocker extension so you can only enable the actual flash content you want - much safer.
