Today, I tried to download new patch. Everything goes well until 23%, then the download progress became seemingly slower. The launcher info said that 59 thousand MB are remaining but that amount didn't change much until 32%. Then an error 101 popped up informing that I don't have enough space on the Hard Drive which is definitely wrong (55 GB of free space on HD). I'd tried to start the repair of the game. But an error 101 again appeared.

The same issue was experienced on the another device with enough Hard Drive space for the patch or repair.
So it looks to me like the launcher is trying to install the entire game's files during the patching. I already had same issue several months ago, during a launch of Elsweyr. And nothing worked to me, just like this time, except uninstalling the whole game, and then applying a patch. I think that something should be done with this quite a common problem. And I'm very disappointed that my last day of free ESO+ with a potential access to the new DLC-dungeons is screwed. Not to mention, the whole day of maintenance before the patch comes live.
