FAST Post Configuration Wizard fail

There’re many error while you are installing FAST Search for SharePoint. Some of them are in the following links.
I got another error while running the post configuration with 2 server 1 admin and 1 non-admin with 1 row and 2 column.
I tried many times but fail.

But finally I got a simple solution:
Restart server after you install FAST for SharePoint binary then run FAST Configuration wizard again then it works!!
