インストールしたにも関わらずFlashが必要となってしまう

Hi,

Please see Enable Flash Player for Google Chrome

The Google support document Adobe Flash isn't working - Chrome Help  also contains this, and more information on troubleshooting Flash in Chrome, and is kept updated by Google.

Also, Please try the following:

• launch chrome
• navigate to chrome://flags/#prefer-html-over-flash
• The flag is most likely set to Default
• change the flag to Disabled
• relaunch Chrome
• Does Flash content display now?

For google Chrome you may access the Flash Player Global Settings using link: Adobe - Flash Player : Settings Manager - Global Security Settings panel. You can also get this link when you right-click any flash content and choose "Global Settings" from the context menu. Then follow below steps to add any location to trusted locations for Chrome.

• On the page opened select "Global Security Settings panel" from the left panel.
• To add any file/folder click on Edit location -> Add location
• Paste the path to the file/folder in the input box below "Trust this location:"
• To delete any location select that location from the menu and choose "delete location" and then confirm

Thanks!
