App Store doesn't launch after El Capitan 10.11.1 update I just installed the 10.11.1 update for Mac OS X 'El Capitan' on my late 2011 MacBook Pro. 
The App Store icon is still visible in my dock, I am able to click it, but the App Store does not launch. 
Is there a way to reinstall the App Store or to fix this in any way?

Update: I have tried restoring "App Store.app" through Time Machine, but the system refuses to remove or replace this file.
This is the kind of 'random' error I would entrust to Onyx [freeware] to tackle.

Run the Utility, supply your admin password, then allow it to run the disk check.

After it has finished, go to Maintenance &amp; the 2nd tab, Permissions. Run the perms check.

If that is not sufficient to fix it, then try the default options in the last tab, Rebuilding.
Reboot.

Navigate to ~/Library/Saved Application State/com.apple.appstore.savedState &amp; delete the contents of that folder, not the folder itself.

 add a comment below if it still doesn't work
