You should not unzip and coyy the installation package by yourself. Let the launcher install.
It removes write protection and during the install process it "back ups" all of your Skyrim files.
All Patches will only be downloadable with the launcher until all big game breaking problems, plot stoppers etc. are resolved.
There is a launcherlog:
C:\programs(x86)\Steam\steamapps\common\Skyrim\EnderalLauncher\system\log\Launcher.log
If you encounter problems with the launcher/updates/installation you can post the log, and we can analyze it.

Launcher: Add a "repair game" button that verifies the integrity of the required files and redownloads files as needed
Thats not that easy to implement, im already busy writing a guide for the wiki on how to remove patches.
