That the update is not working well, could also be caused by high server traffic.
See this post:

SNAP updates not executing

Yes, the updates have been problematic in the recent past. We have observed unusual high traffic on the server which affects the updates of SNAP, especially in the time between 10:00 pm and 9:00 am CET. So it might work if your try to reinstall later. The traffic is not an attack, but there are unusual requests for the DEM files. Probably, someone is processing a lot and is not using the cache for the DEM. We are working on it.
