All of the files installed properly and I had the environment running. While I was working with settings this error came up for both the front end and admin login. Not sure if it is a bug or something I did. Can anyone provide some insight on how to diagnose and repair? Beta 2. 

Take a look at the log files inside the  uploads/logs directory

yes I got that to when I try to run the instiller I getting this Installer Locked

There was a temporary file that was not readable. Reset the container on the server and problem solved.

what is the file was not readable so I can change my

I'm having the same problem. A couple of details would be nice.  Also how to reset "container" ...how is that done.  Thanks.

Look in uploads/logs to find the error. In my case it was a temporary file that could not be written to. The error looked like:

Wed, 26 Nov 2014 23:57:48 +0000 (Severity: 0)
XX.XXX.XX.XXX - http://XXXX.com/robots.txt
Can't create/write to file '/tmp/#sql_2a8_0.MYD' (Errcode: 17)

X's are the IP and domain. To fix this I reset the server. Or I am told you can delete the problem file. 

Mhhh,

personally I've made the convertion:

 

Error

The database tables are UTF-8, collations are correct and there is nothing to convert. You can proceed with the upgrade

Unfortunalty I got the same problem:

 

 

I've checked the logs and I find a lot of table that doesn't exist.

An easy way to resolve this problem?

Thank you

 

 

 

Edit: finally, the problem was on conf_global (take back the old one and the problem was solved)
