Flash player problems in youtube and other sites.

Adobe's Flash Player is needed to access certain types of content on the Web. Generally, you will need the latest version installed on your computer to properly access Flash content, including videos on Youtube.

That's all well and good, but I am guessing the reason you are here is that something has gone wrong. Either Flash seems to install but the content is still not showing, or no matter what you did, Flash wouldn't install on the official Adobe site. Sadly, these are very common issues.

The most frustrating error appears at sites such as Youtube where you see 'Hello, you either have JavaScript turned off or an old version of Macromedia's Flash Player. Get the latest flash player.' In most reports of this Youtube error, it is nothing to with Javascript being turned off, but the Flash Player itself.
Why does the installation on Adobe's site fail?

Well, it could be a range of issues. Here are some common ones:
1. Security software is interfering with the installation
2. User rights are not set at the correct level
3. There is an unknown bug on the Adobe site
4. For some reason, the Flash ActiveX files are not properly registered on the system (common in Internet Explorer 7 and Vista)
5. There is some other Windows Vista or Internet Explorer 7 issue
6. ActiveX controls or security levels in Internet Explorer are set in a way that prevents the installation
7. The protected zone in Windows Vista is causing the problem
8. Something is wrong with the existing version of Flash on your computer. It is probably corrupted and this is preventing the proper installation of the latest Flash player.
9. For the Youtube error 'Hello, you either have JavaScript turned off or an old version of Macromedia's Flash Player. Get the latest Flash player', this is mainly due to a currupted installation of the Flash Player.
Solution to all of the above:
1. First of all check your browser. If you use IE 5, get a higher version.
2. Then check your browser settings. If your settings prevent you from running ActiveX controls, enable them.
For Internet Explorer-
Goto Tools, Internet Options, under 'Security' tab, click Custom Level. Search for 'Run ActiveX controls and plug-ins' and check the 'enable' option.
Firefox users needn't worry. The default settings are perfect for flash player addons.
3. Then get the standalone Flash Player installation file (links are at the end of this article). There are two types: one for Internet Explorer, the other is for Mozilla/Firefox/Netscape.

Still problems?

Okay, you downloaded the standalone installation and the Flash Player is still not working properly. Did you run the installation file you downloaded and close all open windows - including your Web browser? Silly as it may seem, some people forget these steps. Otherwise, it may be an older or corrupt version of Flash that is causing the issue.

Solution: Better use the Flash Player uninstall tool (see the end of the article). Restart your computer and try running the standalone installation file again.
