I am passing my laptop to my son and created a user account for him so he wouldn't be logged in as Admin and screw anything up. After I set up his profile, I had to install Minecraft under his username. It successfully installed and downloaded the launcher but when I start it up, it makes him log in. When he does, it shows his account / username but when you press the PLAY button it just sits there. I thought perhaps the game required to be ran as admin so I changed that setting to give it admin rights when it launched. Same thing, it just sits there. I've ran the repair utility and re-installed the game and after it downloads the launcher, it still doesn't launch. I have logged in under my account (which it recognizes and gives my username) but the game still doesn't launch.
I have NO problems with the game under my Admin profile and can log in as either him or I with no problems there. This is VERY frustrating and shouldn't be this difficult.
Here is the launcher log, where I do see several error statements:

I don't see where to cancel cases. It seems it was a profile issue and for whatever reason, the repairs and re-installs weren't overwriting whatever the issue was. I deleted all of the files in the .minecraft folder and launched the game. It downloaded all new directories and launched with no problems. It looks like this issue is resolved.
