@Svenl77-

Are you trying to install the BP Skeleton Component on an active site? The reason I ask is that you should use the Skeleton Component for developing your own custom BuddyPress plugins. You use the files, code your own solution, then activate your new custom plugin on your development server and test.

There is no reason you would need to reupload WPMU, BuddyPress, or bbPress. The Skeleton Component will not provide any functionality on your site. You simply use it as a general template for coding your own custom plugins.
