How to fix almost all Flash Player issues
A version of Adobe Flash Player is pre-installed with most popular Internet browsers. Sometimes, problems with a Flash Player that's already installed can prevent you from upgrading to the latest player. You can resolve almost all difficulties by taking the following steps:
1. Check System Requirements to ensure your configuration is supported.
2. Make sure you have the latest version of your Internet browser. Installing a new browser can often repair issues with browser installations, and newer browsers may also offer improved security.
3. Remove your existing Flash Player ( see here for a guide: http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157&sliceId=1 )
4. Restart your computer.
5. Download and install the Flash Player from the official Download Center.
