Google chrome browser is very well working in many computers, but still has problems with websites which require authentication, and which requires some new flash players to display their video content. I am talking about flash sites which are not perfectly opening for every person who is using Chrome. Many are getting the message to download the latest version of Adobe flash player to display some content in it.
Rename the file to .zip as its a file which directly interacts with your web browser and changes itself with the extension.
Then extract it to a new folder through winzip. You will see a couple files flashplayer.xpt and NPSWF32.dll which you have copy.
Then go to the plugins folder of your google chrome browser, which might be at -
C/Documents and settings//Local Settings/Application Data/Google/Chrome/Application/Plugins/
Paste both the files in this plugins folder and then close your Chrome browser and restart it.
Try to check whether the installation is done perfectly, by just watching a video in Youtube which requires the latest version of flash player to play the video.
