Hi gamemaddaz,
those scenariopack are from manfried & Bedo (annofrance), it's an self extracted Scenpackage,
after doublklick an Installwindow will open, an you can choose the Scen you will have to install.
Next you can choose the language you need, and the Folder to install (ex. c:/programs/anno)
Then klick install, and all files will be extrackted to the right Annofolder.
Start the Game and you will find them in the Game Menu Singleplayer under the Names you listet.
But notice, the Package is built for the Addon or KE, don't know they works in the normal Version of Anno.
sorry for my bad eng
