for me it helped to move the launcher from another drive to the windows drive. However before the 13th of september it worked properly on its location on the other drive.
While trying to get it to work again on the other drive i had the following error aborting the update:

It might be important that i moved the .minecraft folder to another drive aswell. Which was also no problem before the 13th.
