If you are using a PC with Windows, click on START and then click on All Programs - You should be able to find Internet Explorer in the list.
Use Internet Explorer to reinstall Chrome and Flash Player.
For Flash Player click on the following Adobe link. Go to the bottom of the page where it says, "Still having problems?
Chrome embeds Flash player through its updates and you cant manually uninstall / install flash player in your chrome.
Kindly update / reinstall your chrome to get the latest version of flash player in your chrome.
I am curious to know how did Flash Player get uninstalled from Chrome? If you can please share steps to reproduce how your Flash Plugin got Removed?
Also, Can you open chrome application Goto Chrome://plugins and See if Adobe Flash Player Plugin is Disabled? If yes, kindly enable Flash Player Plugin by clicking the [blue colored]enable link and restart the browser to see if the changes have reflected.
Because Flash Player cannot be uninstalled from Chrome using any uninstaller, as it is embedded part of the app installer/update and can only be removed if you remove the plugin reference from the location on disk. Possibility is that your plugin got disabled and did not get enabled after that.
Please see if it helps. If the above does not work then the only resolve is to update Chrome app. Please let us know if your query got resolved or not.
