Is your phone low on storage? It should have like 1GB free. And what about the battery? Is it charged above 50%?

3 gigs of phone storage available acc. to storage sense. Battery was around 90% at the time.

This exact same thing happened during the Cyan rollout for some devices, and it took MS a bit of time to fix it. You should try again tomorrow, or else report it to Microsoft.

Finally! Update reached my phone on January 24, 2015 at around 12 p.m. IST.

EDIT: same thing happened. Downloaded the update, "preparing to install" went to 20%, then the same message popped up: "couldn't be opened".

Remove SD card before updates...

Update: Used Lumia Software Recovery Tool to upgrade to stock Denim on 11 March.
