how do i uninstall flash player from window 8.1 and reinstall the newer version

Hi,

If you're referring to Internet Explorer on Windows 8.1, Microsoft embeds Flash Player in IE and Microsoft provides all updates via Windows Updates.  Due to this there is no way to completely uninstall it, nor does Microsoft offer a standalone installer for Flash Player for IE on Windows 8.1  The closest thing to uninstalling is to roll-back one of the Flash Player for IE updates you installed.  The following Microsoft KB articles list all Flash Player for IE KB numbers that you can look for in your list of installed updates:

• https://technet.microsoft.com/library/security/2755801‌ - list of all updates from 21-Sept-2012 through 08-Dec-2015 are listed at the bottom
• https://technet.microsoft.com/en-us/library/security/ms16-022‌ - Feb 2016 update
• https://technet.microsoft.com/en-us/library/security/ms16-036.aspx‌ - March 2016 update

If you're referring to a browser other than IE (and Chrome, as Google also embeds Flash Player in Chrome), you can use the uninstaller, posted at Uninstall Flash Player for Windows, to uninstall Flash Player and then download the installer from get.adobe.com/flashplayer
