I tried to install the following addon:

sale_bundle_product

After coping the files to the addon folder and updating the Modules, i tried installing but I always get the following error Message and after this try i'm not able to install any addon anymore. So the Addon destroys my Database.

Is it because the addon is for V6 and not V7? Or wheres the Problem?

Here The Error Message:
