I’m currently having issues with Flash Player and Javascript. YouTube won’t play videos unless I have the new Flash Player downloaded and I need to turn on my Javascript. But when I try to download Flash 10 it almost completes but then says it can’t authenticate user and stops. It doesn’t just affect videos. I can’t use the poker app on Facebook or anything that is Flash based. I tried to delete it and download from scratch, but it won’t even delete. What can I do to fix it? 
I am going to take you through each of the steps for solving this problem. Complete them one at a time starting with the one at the top. Once you do so, you should be able to view YouTube videos and play Poker on Facebook.
Uninstall Previous Version of Adobe Flash Player
Since you have a partially installed version of Adobe Flash Player 10 on your computer, you need to uninstall it completely before moving on. Since Adobe has customized their Adobe Flash Players in a particular manner, you need to use their uninstaller to remove completed or partially-installed versions of Adobe Flash Player from your computer. Visit this link, Uninstall Adobe, at Adobe’s website in order to access the uninstaller. You’ll have to download it. Be sure that you select the one that you need for your computer’s operating system. Specific directions are provided on that page and you should follow them exactly.
Prepare the Computer for Downloads
The best strategy to take whenever you are going to download a new application is to prep the computer first. Clear out all the excess garbage such as unwanted documents and photos and empty the trash bin. Next, make sure that all other programs are closed when you begin the download and installation of the programs that you want.
Install Adobe Flash Player
Visit Adobe’s website at this link, Adobe Flash Player and install the latest Adobe Flash Player.
Install Java
In order to install Java, you need to visit their website at Java Downloads. Just click on the big, bright blue button that says, “Free Java Download.” Follow the prompts and make sure that you select the right download for your operating system. Next, you need to enable Java on your web browser in order for it to work.
How to Enable Java on Internet Explorer
1) Open up your Internet Explorer.
2) Search for “Tools” and click.
3) Select “Internet Options.”
4) Select “Advanced.”
5) Navigate to the option for “Enabling Java” and mark off the box.
6) Select “OK.”
7) Restart your computer to enable the settings.
