You do not need to install Flash player, because screensaver setup / screensaver itself installs the Flash player upon first run.
Problems can occur if the screensaver or its setup is first time run on such systems like Windows NT, 2000, XP from non-administrator account which does not allow screensaver to install Flash player. Explaining error message is shown instead.
Also please note that there have been problems with this, but thay have been fixed in the latest versions, please re-download and re-isntall the product to have the latest version.
Also please report any problems of this kind to our
