Hi guys,

Nowadays, there is Adobe Flash Player on almost every computer with windows 8. Today, I sum up some causes for the windows 8 Adobe Flash Player installation failure problem.

* Security software is interfering with the installation
* User rights are not set at the correct level
* There is an unknown bug on the Adobe site
* For some reason, the Flash ActiveX files are not properly registered on the system (common in Internet Explorer 7 and Vista)
* There is some other Windows Vista or Internet Explorer 7 issue
* ActiveX controls or security levels in Internet Explorer are set in a way that prevents the installation
* The protected zone in Windows Vista is causing the problem
* 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.
* 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 corrupted installation of the Flash Player.
