Check if this registry key exists:

\HKEY_LOCAL_MACHINE\SOFTWARE\Macromedia\FlashPlayer

Then, you can check the installed version (if installed) from here:

\HKEY_LOCAL_MACHINE\SOFTWARE\Macromedia\FlashPlayer\CurrentVersion

Here you can find code on how to check existence of registry key.

Following code return current version string of flash.

private string GetFlashPlayerVersionString()
{
    RegistryKey regKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Macromedia\FlashPlayer");
    if (regKey != null)
    {
        string flashVersion = Convert.ToString(regKey.GetValue("CurrentVersion"));
        return flashVersion;
    }
    return string.Empty;
}

Open the Flash folder (C:\Windows\System32\Macromed\Flash) and whatever is listed there would be your Flash Player files.
