I'm upgrading MyBB from 1.4 to 1.6.
I Uploaded all the files and try to install it by /install/upgrade.php.
When I enter my name and password nothing happen. How can I solve this problem?

Solved the problem.
It didn't work with FF. With IE I logged in without problems.

That isn't solving the problem, that's avoiding the problem.

Please read this thread on login problems. Most likely you just need to clear your cookies in FF.

Clearing cookies didn't work.
IE did the job so there's no problem anymore.
