Simple answer: You can't use Flash player in that environment.
Reason: You can not use ActiveX components from Windows Store apps.
MSDN Says (https://msdn.microsoft.com/en-us/library/windows/apps/jj860457.aspx):
Windows Runtime apps using JavaScript don't support custom Microsoft ActiveX controls. If you need a UI control, use an HTML control, a Windows Library for JavaScript control, or create your own custom WinJS control. If you need to perform custom logic, create a custom Windows Runtime object instead.
It seems like in your frame, the plug-in ActiveX is used. If you are referencing a webpage and if the webpage is using shockwave flash, it might cause the problem. According to MSDN, it is not possible display a page which contains ActiveX plugin in Windows. Since you are not providing a code, I cannot exactly specify the reason, but this is my best guess.
